Gain for Compressed Amplifiers

Examination of two approaches to the concept of gain, differential and ratiometric in compressed amplifiers
Tutorial Gain for Compressed Amplifiers There is growing interest in operating amplifiers into compression to achieve higher power-conversion efficiencies. It becomes constructive then to revisit the concept of amplifier gain, because when an amplifier operates in compression the general assumption that the output signal is directly proportional to the...
