Title:
HYSTERESIS COMPARATOR AND COMMUNICATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2020/218472
Kind Code:
A1
Abstract:
Provided are a hysteresis comparator with which it is possible to obtain desired characteristics even when an IC chip comprising a comparator with no hysteresis or a comparator with a small hysteresis width is used, and a communication circuit. A communication circuit (1) according to an embodiment is provided with: a substrate (2); a coupler (31) provided on the substrate (2); an IC chip (13) which is mounted on the substrate (2) and includes a comparator for comparing the levels of two input signals; an IC chip (70) which includes a second comparator for comparing the levels of reception signals and which is mounted on the substrate (2); and feedback loops (20p), (20n) for positively feeding back outputs of the IC chip (70) to the inputs thereof.
