1.65 Figure P1.65(a) shows two transconductance amplifiers connected in a special configuration. Find vo in terms of v 1 and v2. Let gm = 100 mA/V and R = 5 k. If v1 = v 2 = 1 V, find the value of vo. Also, find vo for the case v 1 = 1.01 V and v2 = 0.99 V. (Note: This circuit is called a differential amplifier and is given the symbol shown in Fig. P1.65(b). A particular type of differential amplifier known as an operational amplifier will be studied in Chapter 2.)
