An amplifier is comprised of two stages. The first stage is a transconductance amplifier with an input resistance of 2k ohms, an output resistance of 100k and a gm=0.002A/V. The second stage is a voltage amplifier with an input resistance of 5k, an output resistance of 18 ohms and a voltage gain of 1.2V/V.
a. Sketch the circuit for this amplifier
b. Determine the overall gain when this amplifier is connected to a source with 50 ohm of output resistance and a 100 ohm load.
