A common connection for a motor power amplifier is shown in Fig. The idea is to have the motor current follow the input voltage, and the connection is called a current amplifier. Assume that the sense resistor rs is very small compared with the feedback resistor R and find the transfer function from Vin to Ia. Also show the transfer function when R f = ?
