Patent Images
1. A method for signal detection, comprising:
- providing a resistor-capacitor (RC) circuit for providing at least one capacitive coupling signal;
receiving a noise synchronizing signal which triggers at least one non-integration period, wherein the RC circuit is affected by a predictable noise in the at least one non-integration period;
providing at least one integration control signal for controlling integration detection on the at least one capacitive coupling signal in a plurality of clock cycles in the at least one non-integration period; and
performing integration detection on the at least one capacitive coupling signal, evading predictable noise, based on the at least one integration control signal.

Abstract
A method and device for signal detection is disclosed. At least one detection period is predefined for detecting a signal of a signal source, a differential signal of a pair of signal sources, or a dual-differential signal of three signal sources during at least one clock cycle, wherein the detection evades the period of a predictable noise.
