REDUCTION OF NOISE AND WEAK AVALANCHE CURRENT INDUCED ERRORS IN BIPOLAR AMPLIFIERS

Examples of circuits and amplifiers include recirculation circuitry to reduce or cancel error currents produced by target bipolar junction transistors (BJTs). In an example, first recirculation circuitry is coupled to the base of a first signal-conveyance BJT and to one of the collector or the emitt...

Summary:Examples of circuits and amplifiers include recirculation circuitry to reduce or cancel error currents produced by target bipolar junction transistors (BJTs). In an example, first recirculation circuitry is coupled to the base of a first signal-conveyance BJT and to one of the collector or the emitter of the first signal-conveyance BJT; second recirculation circuitry is coupled to the base of a second signal-conveyance BJT and to one of the collector or the emitter of the second signal-conveyance BJT; and biasing circuitry is coupled to the first and second recirculation circuitry. The recirculation circuitry may be implemented with BJTs or MOSFETs. Configurations are provided in which error current(s) are recirculated between the base and collector/emitter node of each target BJT.
