Referring to MOS amplifier below, which one of the choices is the small signal voltage gain?
The NMOS transistor in the CS amplifier circuit of the figure is biased to have gm = 1.7 mA/V. Internal capacitances are Cgs = 3.6pF, Cgd = 0.3 pF. (Ignore ro ) Find fH. (Use Miller approximation.) Write full frequency value in Hz. If your result is 153kHz WRITE 153000! or if your result is 15.5kHz WRITE 15500!
Consider the following enhancement MOSFET circuit. The transistor is tested in the laboratory and following results are obtained: VGS(ON) = 2V and ID(ON) = 1 mA. The threshold voltage is also found to be VTH = 1.5 Volts. Find ID, VGS and VDS.
The Vin-Vout transfer characteristic of the circuit with MOSFET in Figure 1.1 is given in Figure 1.2.VT1 = VT2 =1V ; K'n1 = K'n2 ; W1 = 4 um ; L1 = 1 um and L2 = 2 um. Vin= 4 V : Calculate the channel width of transistor M2. For the given MOSFET circuit, Vin-Vout transfer characteristic of this circuit is provided below. Calculate channel width of M2 transistor (W2) if VT1 = V12 = 1 V ; Kn1 = Kn2; W1 = 4um ; L1 = 1um, L2 = 2um and Vin = 4V. Kn = unCox and you need to check whether transistors are operating in saturation or not. M1 and M2 may not operate in the same region.
