For the circuit on the left, KN = KP, Vtn = 1 V, Vtp = -1 V Find the range of bias voltage Vb, to keep M1 in SATURATION and M2 in TRIODE for a. VI = 2 V b. VI = 3 V
For a NMOS having kn = 0.01 A/V2 and Vt = 0.5 V, if VGS = 1 V and VDS = 0.6 V, which operation mode the device is functioning at? cut-off region triode region saturation region linear region
Transistors operate in the saturation region. Please use subscripts to refer to M1 and M2. VB is a bias voltage. Please ignore backgate effect. Please consider ro. Do NOT include any capacitors. Do NOT need to show results in a fully expanded form. (1) Draw the small-signal model of the differential-mode half circuit. Provide a symbolic expression for the differential-mode voltage gain. (2) Draw the small-signal model of the common-mode half circuit. Provide a symbolic expression for the common-mode voltage gain.
