Title:
COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/240339
Kind Code:
A1
Abstract:
Provided is a communication device with a wide range of potentials of signals which can be transmitted and received. This communication device has an amplifier circuit comprising first to fourth transistors, first to fourth bias transistors, first to fourth loads, and first to fourth terminals. The drains of the first to fourth transistors are electrically connected to the sources of the first to fourth bias transistors, respectively. The sources of the first to fourth transistors are electrically connected to the power supply line. The gates of the first and second bias transistors are electrically connected to first wiring, and the gates of the third and fourth bias transistors are electrically connected to second wiring. The first to fourth terminals are electrically connected to the gates of the first to fourth transistors, respectively, and the drains of the third, fourth, first and second bias transistors are electrically connected to the first to fourth loads, respectively.
