Title:
SMALL BROADBAND AMPLIFIER CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/167155
Kind Code:
A1
Abstract:
The present invention relates to a small broadband amplifier circuit. The amplifier circuit according to the present invention comprises: a first amplification stage which includes a first transistor and a second transistor that form a differential pair, and which amplifies and outputs a differential input signal inputted through a first input terminal and a second input terminal; a second amplification stage which includes a third transistor and a fourth transistor that form a differential pair, and which amplifies a signal output from the first amplification stage so as to output same through the first and second output terminals; a first feedforward capacitor for connecting the first input terminal and the first output terminal; and a second feedforward capacitor for connecting the second input terminal and the second output terminal. According to the present invention, provided is the small amplifier circuit, which can implement a wide bandwidth without degradation in chip area, parasitic capacitor, nonlinearity, noise, and power consumption characteristics.
