For the precision rectifier circuit shown in Figure C4 what is the correct operation for the circuitif a Sine wave is applied to the input signal VIN? A. When VIN

is positive the circuit operates as unity voltage follower providing an in-phase sine wave at VOUT. When VIN is negative the circuit conducts but only to one diode drop. B. When VIN is positive the circuit operates as an inverting amplifier providing an inverted sine wave at VOUT. When VIN is negative the circuit is driven to very close to zero due to amplifier gain reducing the diode drop voltage, C. When VIN is positive the circuit operates as unity voltage follower providing an in-phase sine wave at VOUT. When VIN is negative the circuit is driven to very close to zero due to amplifier gain reducing the diode drop voltage, D. When VIN is positive the circuit operates as an inverting amplifier providing an inverted sine wave at VOUT. When VIN is negative the circuit conducts but only to one diode drop.
