In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Abstract: This paper surveys the history of the electric-circuit representation of the transistor over the past fifty years. During the first two decades after the transistor was announced in 1948, ...

This repository contains the design, analysis, and simulation of single-stage amplifiers and a differential amplifier. The project explores the common source amplifier with different loads and the ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

There are many applications for one or two transistors. These can include voltage and current amplification useful for interfacing between other system blocks (perhaps ICs). Described in this series ...
