The large-signal voltage gain

Reference no: EM131037855

8.47 Consider the circuit shown in Fig. 8.16(a), using a 3.3-V supply and transistors for which /Vt /= 0.8 V and L = 1 μm. For Q1:
k1n =100 μA/V2, VA =100 V, and W =20 μm. For Q2:
and Q3:
k1p = 50 μA/V2 and /VA / = 50 V. For Q2:
W = 40 μm. For Q3:
W = 10 μm.
(a) If Q1:
(b) is to be biased at 100 μA, find IREF. For simplicity
(b) What are the extreme values of vO for which Q1:
and Q2:
just remain in saturation?
(c) What is the large-signal voltage gain?
(d) Find the slope of the transfer characteristic at vO =VDD/2.
(e) For operation as a small-signal amplifier around a bias point at vO = VDD/2, find the small-signal voltage again and output resistance
