For the MOSFET bias circuit shown, what value of Rs in kilohms is needed to set the drain bias current to 0.66mA ? Assume that the transistor is in the saturation region, and use: Vdd = 10V, Vss = -8V, Vg = 1.8V, Vt = 0.8V, and Von = 0.30. (Remember that Von = Vov = Vgs-Vt) Neglect the effect of channel-length modulation and body effect.
For the MOSFET bias circuit shown, what is the drain current, Id, in milliamps? Assume that the transistor is in the saturation region, and use: Vdd = 6 V, Vss = -9 V, Vg = 1.5 V, Rd = 2.6 kohm, Rs = 7.5 kohm, Vt = -0.5 V, and |Von| = 0.15. (Remember that |Von| = |Vov| = |Vgs|-|Vt|) Neglect the effect of channel-length modulation and body effect.
Consider a CG amplifier as shown below. Assume the following parameters: Vdd = 3V, kn = 2mA/V^2, Vt = 0.4V, and Rd = 10 kΩ. Ignore channel length modulation and body effect, VB is a dc bias and equal to 1.1V. The input signal applied to the amplifier is given by Vin = 0.25V+0.01sin(2pi x 10kHz x t). a. Calculate the de voltage at the output b. Calculate small signal gain of the amplifier
