A Novel Design Based Approach of High Performance CMOS Based Comparator Using PSpice
نویسندگان
چکیده
A new continuous-time CMOS current comparator having high speed and low power is proposed as an important component of current mode signal processing unit. It comprises of CMOS complementary amplifier with a feedback MOS resistor, two resistive load amplifiers and two CMOS inverters. Short response delay, low power consumption and small area are some of its features. Due to the absence of bias current and voltages, the circuit is robust to process deviations. The superiority on speed/power ratio over other existing high performance CMOS current comparator can be verified by PSPICE simulation result with 1.2μm CMOS process.
