Mullard Circuits for Audio Amplifiers is a famous book by the Technical Services Department of Mullard Ltd, a British valve manufacturing company. First published in 1959 and then reprinted several times it contained a number of designs by Mullard engineers for high quality audio amplifiers, which were to be used by amateur constructors as well as by manufacturers as the basis for many ...
The first class-D amplifier was invented by British scientist Alec Reeves in the 1950s and was first called by that name in 1955. The first commercial product was a kit module called the X-10 released by Sinclair Radionics in 1964. However, it had an output power of only 2.5 watts.

Circuit diagram symbol for a representative op amp. Pins are labeled as listed above. An operational amplifier (often op amp or opamp ) is a DC-coupled electronic voltage amplifier with a differential input , a (usually) single-ended output, [ 1 ] and an extremely high gain .
The circuit can be represented in a more generic way by replacing the amplifiers with a generalised transconductance amplifier as shown. Generic representation of one stage of a double-tuned amplifier and part of the following stage where (omitting the stage number suffixes), g m is the transconductance of the amplifiers
Basic opamp diode log amplifier. The basic opamp diode log amplifier shown in the diagram utilizes the diode's exponential current-voltage relationship for the opamp's negative feedback path, with the diode's anode virtually grounded and its cathode connected to the opamp's output , used as the circuit output.
For the case when the common-base circuit is used as a voltage amplifier, the circuit is shown in Figure 2. The output resistance is large, at least R C || r O, the value which arises with low source impedance (R S ≪ r E). A large output resistance is undesirable in a voltage amplifier, as it leads to poor voltage division at the output.
