Abstract
The basic circuit block diagram of CMOS current mode sum and subtract circuit is present in this paper. The purpose circuit consists of the invert current circuit and the basic current mirror. The outputs of the circuit are the summing of the both input current [lx+ly] and also the subtract of the both input current [lx+(-ly)]. The SPICE simulation results of the electrical characteristics with level 7 (BSIM3 model version 3.1) MOSFET transistor model of the circuit such as the input dynamic range, the frequency response and some system application have been shown and analyzed.
