D 8.6 The current-steering circuit of Fig. P8.6 is fabricated in a CMOS technology for which μnCox = 400 μA/V2, μpCox = 100 μA/V2, Vtn = 0.5 V Vtp = −0.5 V, VAn = 5 V/μ m, and |VAp | = 5 V/μm. If all devices have L = 0.5 μm, design the circuit so that I REF = 20 μA, I2 = 100 μA, I3 = I4 = 40 μA, and I 5 = 80 μA. Use the minimum possible device widths needed to achieve proper operation of the current source Q2 for voltages at its drain as high as +0.8 V and proper operation of the current sink Q5 with voltages at its drain as low as –0.8 V. Specify the widths of all devices and the value of R. Find the output resistance of the current source Q2 and the output resistance of the current sink Q5.
