Direct coupled high gain amplifier
Did you know?
WebThe voltage gain of the non-inverting amplifier can be calculated as: A = A + (R2/R1) Non-inverting amplifiers have high input and low output impedances. It is also regarded as the voltage amplifier. DC Amplifiers. DC or Direct Coupled Amplifiers are used for amplifying low-frequency and direct-coupled signals. Direct-coupled amplifiers constructed in the conventional form of single-ended amplifiers connected in cascade suffer from drift of the output voltage with time and temperature. In many high-gain applications it is necessary to provide offset adjustments to deal with drift. The drift problem can be overcome by using differential amplifiers.
