Transistor introduction

A transistor is a solid semiconductor device (including diodes, transistors, field effect transistors, thyristors, etc., sometimes referred to as bipolar devices), and has various functions such as detection, rectification, amplification, switching, voltage regulation, and signal modulation. . The transistor acts as a variable current switch that controls the output current based on the input voltage. Unlike ordinary mechanical switches (such as Relay, switch), transistors use electrical signals to control their opening and closing, and the switching speed can be very fast, the switching speed in the laboratory can reach more than 100GHz.
