Hi everyone I am currently working on a square circuit and the circuits consists of current mirrors. The input voltage will result in a output square current function being obtained. However, At the output, there is one p and n mos transistors (one at top, one at bottom) and this 2 transistors are supposed to provide a sum current which will then be the output current ( output junction at the middle of the 2 transistors). However, it seems that for both LTspice and electric, there will be just one single current flowing through the transistors, making the current mirror to fail, may i know anyone has any method to solve this problem. For LTspice, I had tried to put an ideal inverting op amp at the output, the voltage across R1 (ideal op amp gain of R2/ R1=1) is set to 0 so that there will be a short circuit, causing current from n transistor and p transistor to flow directly across the op amp, this can help to solve the single current flow problem. However, for Electric, I do not have the processes or parameters for the transistors within the op amp, causing me to unable to use similar approach. May I know anyone has any better solution to solve this problem.Thank You very much
