Buffer stage amplifier
WebMar 13, 2012 · March 13, 2012. Cascode amplifier is a two stage circuit consisting of a transconductance amplifier followed by a buffer amplifier. The word “cascode” was originated from the phrase “cascade to … WebA buffer circuit comprised of two matched stages is provided. The first stage develops a replica voltage that is used in the second stage as the input to a wide-band amplifier. The combination of the two feedback loops in the circuit result in improved linearity. The first amplifier dominates for moderate frequencies while the second amplifier takes over for …

WebQ1: This BJT is the heart of the first amplification stage, a common-emitter (CE) voltage amplifier. Its job is to transform variations in the base current caused by the microphone voltage variations arriving over C1 into current variations through the collector-emitter circuit R3, R4 and C2.
