*REGENERATION REVISITED
The Tesla Connection
by Gary Peterson*
*P*ick up nearly any book on the principles of radio, turn to the
chapter on receivers and you will see it—the primary objectives to be
achieved in detector design are sensitivity, selectivity and stability.
Historically, some of the very first detectors consisted simply of a
tuned circuit into which was incorporated a sensitive device known as a
coherer. With the introduction of two and three element vacuum-tube
circuits as a replacement for the earlier coherer based designs further
important steps were taken towards the advanced receivers of today. One
of the first improvements in the triode, or Audion, based circuit was
dubbed the Regenerative Detector. In this configuration, conceived of
by Edwin H. Armstrong in 1912, a portion of the signal from the plate
circuit was coupled as positive feedback to the tuned antenna tank
circuit. The result was greatly increased receiver sensitivity.
Focusing on receiver sensitivity or the ability to pick up weak signals,
it is important to understand the antenna design concept of "effective
area." This refers to the fact that a tuned antenna may have an
effective area that is larger than its geometric area. The phenomenon
was first explained by Reinhold Rudenberg in 1908 [1] and the
description has been expanded upon over the years by many other
writers. In the words of Dr. John F. Sutton from his recent active
antenna patent, "Rudenberg teaches that the antenna interacts with the
incoming field, which may be approximately a plane wave, causing a
current to flow in the antenna by induction. The [antenna] current, in
turn, produces a field in the vicinity of the antenna, which field, in
turn, interacts with the incoming field in such a way that the incoming
field lines are bent. The field lines are bent in such a way that the
energy is caused to flow from a relatively large portion of the incoming
wave front, having the effect of absorbing energy from the wave front
into the antenna from a wave front which is much larger than the
geometrical area of the antenna." One of the factors that limits
antenna current is the ohmic resistance of the tuned detector tank
circuit and the antenna wire itself. Regeneration is a means of
increasing antenna current by counteracting the resistance of the entire
antenna circuit. By the introduction of what might be called negative
resistance through the addition of a feedback loop, antenna-field
interaction is increased and energy is absorbed from a greater area of
the incoming wave front.
How does Nikola Tesla fit into this picture? In a New York American
article of Sept. 3, 1911 while speaking of his receiver design he said
that it "concentrates the energy transmitted over a wide area into the
device." This statement was made about one year prior to Armstrong's
discovery related to RF feedback to the grid-antenna circuit. In fact,
we can see that Tesla recognized the utility of the feedback technique
to introduce negative resistance into antenna circuitry and had
incorporated it in his designs as early as 1899. On August 3 of that
year he recorded a number of receiver circuit arrangements in which RF
currents were fed back from the secondary side of a resonant transformer
to a coherer located on the transformer's primary side. In this form of
receiver, which Tesla had described as using a "self-exciting process,"
the coherer was made significantly more sensitive to incoming signals.
In his own words, "This method has been found excellent and will have
besides telegraphy many valuable uses since by its means effects, too
feeble to be recorded in other ways, may be rendered sufficiently strong
to cause the operation of any suitable device." So it may be said that
Tesla anticipated the technique of regenerative feedback to increase
detector sensitivity.
*Figure 1. "In Diagram 3. the form of connections is illustrated which
was found most convenient for experimentation. An independent sensitive
relay is used and adjustable dead resistances r and r' in primary and
secondary circuits. The inductance L is also made adjustable and so is
also break device d though this is not indicated in the diagram."*
The basic regenerative circuit is not often used in present day receiver
front ends for a number of reasons, the most significant of these being
an inherent form of instability. Maximum sensitivity is achieved at a
point just before the detector breaks into oscillation and in the
original configuration this could be initiated by something as simple as
wind shifting the antenna. As the appearance of oscillating
regenerative front ends on the broadcast bands became a more and more
regular occurrence a decision was made to phase the regenerative
detector out of general service. A related difficulty is the need to
reset the degree of regeneration as the detector is tuned. In spite of
these problems the increases in sensitivity to be gained through the
incorporation of this powerful technique have not been totally lost on
the minds of the engineering community. Goaded on by this
understanding, a few years ago Dr. Sutton set out to develop a positive
feedback antenna circuit configuration that would be very sensitive to
low level fields while at the same time being resistant to the influence
of stray capacitive and inductive reactances. Figure 1 is a schematic
diagram of a circuit that was developed which satisfies these requirements.
Typical values for the components shown are: R1=10k, R2=100k, R3=10 S,
R4, R5, R6, R7=10k, R8=30k, and C1=1000 :fd. Amplifiers A1, A2 and A3
may be Precision Monolithics OP-27

shielding is provided to reduce capacitive coupling between the two
windings.

As the specific design problem was development of an optimized broadband
ELF magnetic field sensor, an active antenna with a wide frequency
response was also a criterion. This posed a design challenge as in a
typical tuned antenna circuit significant antenna current, and thus
maximum sensitivity, is only present with conditions of resonance.
Under normal circumstances, peak resonance occurs at some very specific
frequency where inductive reactance is canceled out by capacitive
reactance. The innovative solution was to add a second feedback loop to
the circuit which introduces negative inductive reactance that works in
place of circuit capacitance to tune out inductive reactance. This
results in an antenna circuit with a resonance that, under ideal
conditions, would have an infinite bandwidth.
All in all, the same conditions which exist in a passive narrow band
tuned antenna, vis-—-vis resonance, antenna current and effective area,
are electronically created in the antenna coil. Furthermore, the active
resonant antenna has a bandwidth which is in the order of four decades
wider. The net result is a unique active antenna circuit that can be
reliably adjusted in which total antenna circuit impedance is much
smaller than appears to have been obtained with any other configuration
to date.
A detailed description of how the negative resistance, negative
inductance circuit works, including a differential form of the active
antenna circuit and other pertinent information, can be found in U.S.
