DIFFERENTIAL amplifiers for CMOS technology with low supply voltage

摘要

When using korotkokanalnogo CMOS process supply voltage exceeds 1.8 V, which imposes restrictions on the number of characteristics of analog devices, in particular to the input common mode signal range and magnitude of the output voltage of the differential amplifier. The main objective of the proposed utility model is to extend the range of input phase signal and the amplitude of the output voltage in a voltage limit korotkokanalnoy CMOS technology. Technical result is achieved by using a transistor amplifier circuit with an electrical connection to the gate pocket, which are characterized by the large slope of the transient response and minimal turn-on voltage. The invention relates to the field of radio engineering and may be used as analog signals, amplification device, the structure of analog and analog-to-digital circuits of various functionality with low supply voltage.
