No need to solve example 8.4

8.46 The power supply of the CMOS amplifier analyzed in Example 8.4 is increased to 5 V. What will the extent of the linear region at the output become? Example 8.4 Consider the CMOS common-source amplifier in Fig. 8.16(a) for the case Vpp 3 V, VPVP0.6 V, 14,dar 200 ??/V2, and 14,dax-65 ???". For all transistors, L-0.4 ?m and W-4 ?m. Also, %. = 20 v. ?Yul = 10 ?, and IREF-100 ? A. Find the small-signal voltage gain. Also, find the coordinates of the extremities of the amplifier region of the transfer characteristic- that is, points A and B SG 03 REF Ur

Explanation / Answer

Linear region at the output = 50% of power supply.

Since, power supply is increased by 5V. This implies that, the extent of the linear region at the output will increase by 50% of the increased supply i.e. 5V.

=> 50% of 5V = 0.5 X 5V = 2.5V

Hence, the linear region will be increased by 2.5V for CMOS amplifier.
