During the engineering course, I had read and seen the Thevenin equivalent circuit theory and example of the circuit, I completely forgot it. As I now read more often circuit and circuit schematic to find out how they work, I have started to understand a bit more and can figure out why an…

Differential amplifiers are key components in many electronic circuits, enabling the amplification of the difference between two input signals while rejecting common-mode noise. They are essential in applications like audio processing, instrumentati…
A limiter is a circuit that maintains a constant amplitude for all input signals exceeding a critical threshold. In the context of an FM receiver , its primary role is to eliminate any residual unwanted amplitude modulation and amplitude variations …
In FM radio receiver, the received signal amplitude reaching the receiver antenna can be low as 1uV and if noise level can also be low as 1uV. This presents a problem such low level signal enters the RF mixer . So RF amplifier are used to amplify t…
JFET transistor are typically used in RF amplifier stage in radio receivers. Although there are other types of transistors like BJT, MOSFET and maybe diode can be used. In this blog post, it is explained why is JFET preferred transistor compared to…

Learn how to design BJT amplifier Quickly using Online Calculator. BJT Amplifier with Voltage divider biasing Below is video that teaches how to use the online voltage divider biasing BJT amplifier online calculator.
Many times we need to design DC level shifting circuit to shift voltage level from one to another such as from +5V to 0V as is done in Operational Amplifier with minimum change in the ac voltage signal that rides on such dc signal. Here are some of …
Here I am sharing a LED sign board schematic diagram which is simple to build. This can be easily be made on a breadboard. The LEDs are connected in parallel. That is each LED anode is interconnected and then connected to the +ve terminal of the bat…
