A mixer is implemented as shown in the figure. The resistor RD=2k, kn=2mA/V2, VDD=10V, Vt=1 V. The MOSFET is placed in saturation mode by a DC bias voltage of 2 V. If two signals, VRF = 1.0cosw1t and VLO = 0.6cosw2t (both VRF and VLO are in V ) are applied to the input of this simple mixer, what is the amplitude of the DC voltage (V) at the drain of the MOSFET? Approximate your answer to two decimal points. Tip: This DC voltage may be different from the DC bias voltage at the drain.
