In the previous post I explained BJT biasing, in this article I have explained what is transistor or BJT saturation and how to determine the value quickly through formulas and practical evaluations. What is Transistor Saturation The term saturation refers to any system where the specification levels have attained the maximum value. A transistor may be said […]

DC Biasing in Transistors – BJTs
In simple terms, biasing in BJTs may be defined as a process in which a BJT is activated or switched ON by applying a smaller magnitude of DC is across its base/emitter terminals so that its is able to conduct a relatively larger magnitude of DC across its collector emitter terminals. The working of a […]
UP DOWN Logic Sequence Controller Circuit
Using a set of latch/reset networks it becomes possible to allow a logic to move in a forward sequence, switching ON a given set of outputs HIGH, in response to an alternating input clock. And once the max limit is reached, the input clocks begin shutting down or withdrawing the sequence in the opposite order. […]
Motorcycle Button Start Locking Circuit
In this post I have explained how to modify an existing button start system in motorcycles so that it’s disabled as soon as the engine has started and gained the required minimum amount of RPM. The idea was requested by Mr. Jordan Circuit Requirements I just discovered your splendid site/blog with focus on education about […]
How to Connect MOSFET with Arduino using BJT as Level Shifters
The interfacing of power devices like BJTs, and MOSFETs with Arduino output is a crucial configuration which allows switching high power loads through low power outputs of an Arduino. In this article we elaborately discuss the correct methods of using or connecting transistors like BJTs and mosfets with any microcontroller or an Arduino. Such stages […]
2 Simple Bidirectional Motor Controller Circuits Explored
A circuit which allows a connected motor to operate in clockwise and anticlockwise directions through alternate input triggers is called a bidirectional controller circuit. The first design below discusses a Full bridge or H bridge based Bidirectional motor controller circuit using the 4 opamps from the IC LM324. In the second article I have explained […]
