Design a basic MOSFET diff-amp with an active load and constant current-source biasing. The bias voltages are to be ±3 V and the maximum power dissipation is to be limited to 2 mW. The open-circuit differentialmode voltage gain should be |Ad| = 180 and the common-mode rejection ratio should be CMRRdB = 80 dB.
Use appropriate transistor parameters. Specify bias currents, minimum λ values, and the minimum output impedance of the current source. Design the current source to achieve the required output impedance.
