TRAPATT oscillations in a p-i-n avalanche diode

P-i-n avalanche diode trapped plasma avalanche triggered transit /TRAPATT/ oscillations characteristics and voltage waveform under square wave driving current, using computer program

Parker, D.↗

Temperature compensation of light-emitting diodes

Circuit which includes a thermistor-resistor combination to compensate for temperature fluctuations by supplying input voltage to light-emitting diode, maintains constant light output. Similar circuits can be used for temperature-induced variations in photodiode applications.

Deboo, G. J.↗

Diode-quad bridge for reactive transducers and FM discriminators

Diode-quad bridge circuit was developed for use with pressure-sensitive capacitive transducers, liquid-level measuring devices, proximity deflection sensors, and inductive displacement sensors. It may also be used as FM discriminator and as universal impedance bridge.
