EXAMPLE 10.10 Figure 10.27 shows a feedback current amplifier formed by cascading an inverting voltage amplifier u witha MOSFET Q. The output current I, is the drain current of Q. The feedback network, consisting of resistors R, and R, senses an exactly equal current, namely, the source current of Q, and provides feedback current signal that is mixed with I, at the input node. Note that the bias arrangement is not...
