A student proposes a hybrid chip where the CMOS inverter above is used for both digital logic and analog amplification. Consider the following CMOS inverter. The transistor parameters are as follows: K_n=K_p=0.2 mA/V^2, V_Tp=-0.4 V V_Tn=0.4 V. The corresponding input-output characteristic is of the following form: In these questions we consider the same CMOS inverter of the pri0r part, but now we assume realistic value for lambda_n and lambda_p as follows: lambda_n = 02 V-1 and lambda p = 0.02 V-1. Assume that all the other transistor parameters remain the same. In this scenario the input-output characteristic curve looks like this A student proposes a hybrid chip where the CMOS inverter above is used for both digital logic and analog amplification. In the amplifier function, let's assume that the input voltage is the sum of a DC bias equal to 1.25 V and a very small signal (Vsmall (t)) as shown in the figure. In this scenario, what is the expected small-signal voltage gain (amplification factor) (under no load or open circuit at the output node)?
