Abstract

A low-voltage and low-power consumption of current-mode operational amplifier designed with level shifter technique is presented. This simple integrator is built up with only 9 typical MOSFETs and 2 bias current sources. To minimize the influence of common-mode signal and noise to the signal processing, the differential structure is applied. As the result of simulation, it has been confirmed that the proposed circuit works as integrator in the frequency range 0-1.6MHz at 1.5V supply voltage and consumed DC power at maximum 8.85muW with 1.2mum double-poly CMOS process
