    ...the idea of using a constant gm bias circuit to bias the amplifier. Design the bias network and determine the dimensions of all transistors. Due to area constraints, you can only use a resistor up to 40K Ohms and a maximum L of 10um. Also, do not forget that K > 20 is forbidden and your circuit needs a startup circuit! (Hint: Consider using m=4 to simplify
