Digital-to-Analog (DAC), Analog-to-Digital (ADC) Converter Circuits Explained

Last Updated on June 10, 2022 by Swagatam 3 Comments

A digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a circuit designed to convert a digital input signal into an analog output signal. The analog-to-digital converter (ADC) works in the opposite way and transforms an analog input signal into a […]

BJT Transfer Characteristics

Last Updated on May 8, 2022 by Swagatam Leave a Comment

In BJTs or bipolar transistors, transfer characteristics can be understood as plotting of an output current against an input-controlling magnitude, which consequently exhibits a direct “transfer” of variables from input […]
