One particular application uses log/antilog circuits to reduce the number of bits needed to digitally represent an analog voltage.
WitrynaLog Amplifier: There are several applications of log and antilog amplifiers. Antilog computation may require functions such as ln x, log x or sin hx. Uses: Direct dB display on a digital Voltmeter and Spectrum analyzer. Log-amp can also be used to compress the dynamic range of a signal. A grounded base transistor is placed in the feedback … Witryna7 lut 2024 · Antilogarithmic Amplifier using Matched Diode. The figure of anti-logarithmic amplifier using matched diode is shown in figure below. Two matched diodes are used here, where one diode (D 1) is connected in feedback path and second diode (D 2) is connected to inverting input of op-amp (A2) in reverse bias mood as …
