Driving an electronic instrument

摘要: Circuitry includes a pre-amplifier having differential output, where the output corresponds to common mode voltage; multiplexer including sets of transistors, each which has control input; comparator input terminals, first terminal terminals receive signal that is based on an multiplexer, and second threshold compensation circuit produce divided voltage varies in accordance with variations amplifier predefined use affect for comparator. Signals are applicable corresponding inputs transistors.
