WebJul 6, 2006 · A simple modification of the MOS voltage follower is introduced that provides it with efficient class-AB operation. The modified circuit has dynamic output currents and bandwidth that are essentially larger than the conventional MOS voltage follower. WebSep 17, 2024 · The basic building block of analog/mixed-signal circuits which is used as a buffer is known as a voltage follower. But, it shows several limitations such as non-symmetrical slew rate, distortion with the increase in frequency, and output resistance is also not low enough [ 1 ].
WebDec 5, 2016 · Class B amplifiers produce significant crossover distortion, which is highly undesirable. A small amount of bias can be added to a Class B amplifier to form a Class AB amplifier, which has considerably less crossover distortion than a Class B amplifier. Single Class AB amplifiers can be combined to form push-pull Class AB amplifiers.
WebThe source terminal is connected to both the 2.2KΩ load resistor and Scope input 2+ (Single Ended). The other end of the load resistor is connected to the negative (Vn) supply. To measure the input to output error, channel 2 of the scope can be used differentially by connecting 2+ to the gate of M1 and 2- to the source. Figure 1 Source Follower. WebNov 1, 2012 · A class AB version of the conventional super source follower (SSF) is described. The circuit greatly increases slew rate (SR) and current efficiency, maintaining …
WebA simple way to eliminate crossover distortion in a Class B amplifier is to add two small voltage sources to the circuit to bias both the transistors at a point slightly above their cut-off point. This then would give us what is commonly called an Class AB Amplifier circuit. However, it is impractical to add additional voltage sources to the ...
