Design a basic MOSFET diff-amp with an active load and constant current-source biasing. The bias voltages are to be \(\pm 3 \mathrm{~V}\) and the maximum power dissipation is to be limited to \(2 \mathrm{~mW}\). The open-circuit differentialmode voltage gain should be \(\left|A_{d}\right|=180\) and the common-mode rejection ratio should be \(\mathrm{CMRR}_{\mathrm{dB}}=80 \mathrm{~dB}\). Use appropriate transistor parameters. Specify bias currents, minimum \(\lambda\) values, and the minimum output impedance of the current source. Design the current source to achieve the required output impedance.
