BJT Emitter-Follower – Working, Application Circuits
In this post we learn how to use a transistor emitter follower configuration in practical electronic circuits, we study this through a few different example application circuits. An emitter follower […]
How Supercapacitors Work
In this post we are going to understand what a supercapacitor is, how closely similar or different to an ordinary capacitor, where it is used and we will be doing […]
Calculating Capacitor Charge/Discharge Time using RC Constant
Capacitor charge and discharge periods is usually calculated through an RC constant called tau, expressed as the product of R and C, where C is the capacitance and R is […]
Transistor Stray pickup False Triggering Problem
The article explains how to make any BJT or mosfet based circuit free from stray signal pickup and false triggering by simply attaching a filter resistor or a capacitor across […]
How to Make a Zero Crossing Detector Circuit
Making a zero crossing detector circuit is actually very easy and it could be effectively applied for protecting sensitive electronic equipment against mains switch ON surges. A zero crossing detector […]
