Buffer Amplifier

This circuit is utilized for analog signal selection or time division multiplexing. The feedback signal places the selected amplifier channel in a voltage follower (non-inverting unity gain) configuration, providing very high input impedance and low output impedance. The single...

700W Amplifier. Adjusting the amplifier power to 700W appears straightforward, yet it is essential to consider the adjustment of the driving transistors and the frequency offset engagement. It is necessary to modify the current protection circuit that safeguards the...

The circuit design features a unique technology and a reasonable structure utilizing all-discrete components with a Class A FET output. The complete circuit includes an input stage, an output stage, and a power level circuit to enhance performance, along...

In a grid-driven amplifier, it is essential to match the low impedance of the driving transmitter (typically 50 ohms) to the high impedance input of the tube (usually several thousand to several million ohms). The signal from the input...

This is the schematic of the final design including the tone stack but leaving out the volume, balance, and sonic controls. The right half of the circuit is John Broskie's original White cathode amplifier with a pair of 5687s...

A back radiation small buffer amplifier is presented, featuring an inverse radiation small buffer amplifier configuration. The circuit is composed of three transistors connected in series, functioning as a buffer amplifier. This design can be utilized in output amplifiers...
