The construction of the circuit was focused on emphasizing and amplification of video signals to obtain more clarity of picture frequencies. BC547 – NPN small signal transistors designed for general ...

Amplifiers in cascode Configuration and their variations are generally used to overcome Miller Capacitance, improve the small signal gain and output impedance. Increasing number of transistors in ...

Amplifying the small signals produced by sensors in a low-noise circuit is a very common but difficult problem. Designers will often use an operational amplifier (op amp) with bipolar inputs to ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
