Logarithmic Gain Amplifier at Kara Walton blog

Logarithmic Gain Amplifier. The figure shows a simplified block diagram of a log amp. Figure 1 shows an amplifier that provides a logarithmic output for. Vout = vy log(vin/vx) eq. These amplifiers have linear gain,. Basic multistage log amp architecture. A log amp must satisfy a transfer function of the form. As the input signal increases, the last stage will limit. Note that the transistor is used to turn the input voltage into an input current, with a log function. The core of the device is a cascaded chain of amplifiers. 1 over some range of input values which may vary from 100:1 (40 db) to over 1,000,000:1 (120 db). This current then feeds rf, which. They compress input signals having a large. It will now make a fixed contribution to the output of the summing amplifier, but the incremental gain to the. The theory and construction of these circuits are actually readily understood. 1 theory and applications of logarithmic amplifiers.
