Abstract
An electronic circuit includes: a differential amplifier circuit into which a digital input signal and a reference signal are fed; a feedback circuit outputting an average of amplitude of the input signal; and a peak holding circuit outputting a signal held based on an output signal of the feedback circuit as the reference signal.
Claims7
An electronic circuit comprising:
- a differential amplifier circuit into which a digital input signal and a reference signal are fed;
- a feedback circuit outputting an average of amplitude of the input signal;
- and
- a peak holding circuit outputting a signal held based on an output signal of the feedback circuit as the reference signal wherein
- the peak holding circuit comprises a reset circuit setting the reference signal to be a constant value.

A communication system communicating with communication paths comprising:
- a pulse converting circuit that converts a signal from one of the communication paths into a pulse train by comparing the signal with a reference value;
- an average generating circuit that generates an average of amplitude of an input signal of the pulse converting circuit based on the input signal of the pulse converting circuit;
- and
- a peak holding circuit that outputs a signal held based on the output of the average generating circuit as the reference value,
- the peak holding circuit resetting an output of the peak holding circuit to be a given value based on a reset signal generated in a period where the communication path is switched to another one from the one of the communication paths.
