Abstract
An electronic circuit comprises an analog-to-digital converter (ADC) circuit. The ADC circuit includes a pre-amplifying transistor and a quantizer circuit. The pre-amplifying transistor includes a base, an emitter and a collector. The pre-amplifying transistor is configured to receive an input voltage at the base that varies logarithmically; and produce an output voltage at the collector according to a comparison of a reference voltage and a difference between the input voltage and a voltage at the emitter. The quantizer circuit is operatively coupled to the pre-amplifying transistor and is configured to generate a digital value for the input voltage using the output voltage produced by the pre-amplifying transistor.
