An antilogarithmic amplifier can be constructed using an operational amplifier (op-amp) with a diode or a transistor in the feedback path. The key idea is to exploit the exponential current-voltage relationship of a diode or BJT to produce an output voltage proportional to the antilogarithm of the input voltage. Circuit Description: 1. Use an op-amp in an inverting configuration. 2. Connect the input voltage (V_\text{in}) to the inverting input through a resistor (R). 3. ______ ________ ________ ______ ________ _____ _______ __________ ____ ___.
