Abstract: This paper proposes a topology of amplifier-less temperature sensor based on BJT. Two base-emitter voltages are connected to the input and the reference voltage of the ADC. The signal ratio ...

This Pre-Amplifier circuit is a minimalistic design, a.o. inspired by valve design, which should help sound clarity. The circuit counts 5 transistors, has 0.1% distortion (expected from 60dB loop gain ...
