Simple Logarithmic Amplifier Circuit

The performance of the logarithmic operational amplifier, the circuit diagram of which is shown in figure 1, is best seen from its input/output characteristic shown in figure 2. For small input voltages, the amplification is high; when the input voltage rises, the amplification drops off and finally remains almost static for further increases in input […]

Constant Volume FET Amplifier Circuit

In numerous occasions it is desirable to obtain an amplifier that gives an output signal of constant amplitude for numerous input signal levels and with the very least distortion. A traditional way out of this challenge is to use a nonlinear amplifier. An operational, as an illustration, run as a nonlinear amplifier if 2 antiparallel […]
