Current Source and Current sink are two major terms used in electronics design, these two terms dictate how much current can leave or enter a terminal. For example, the sink and source current of a typical 8051 Microcontroller digital output pin is 1.6mA and 60uA respectively. Meaning the pin can deliver (source) up to 60uA when made High and […]

When designing an electronic circuit, there are lots of situations when a circuit requires different values of voltage and current sources. For example, when setting the preset voltage for an Op-Amp, it is very common to use a potential divider circuit to obtain the required voltage values. But what if we need a specific value of current?

An inverter is a circuit that converts Direct Current (DC) to Alternating Current (AC). A PWM inverter is a type of circuit that uses modified square waves to simulate the effects of Alternating Current (AC), which is suitable for powering most of your household appliances. I say most-of because there generally exist two types of inverters, the first type is the so-called a modified square

Often times, we need to control bass, treble, and volume of our audio signal before passing it through amplification stages to prevent sound distortion. The circuit that amplifies the audio signal before it enters the main speaker amplifier is called an Audio Preamplifier. The use of an audio pre-amplifier ensures good audio quality and provides options to modify

A crude way to power your DC circuits with AC mains is to use a step-down transformer for stepping down the 230V mains voltage and adding a couple of diodes as a bridge rectifier. But due to the huge space size and other drawbacks, it cannot be used for all purposes. Another most popular and professional

Tone control or Active equalizer circuit especially bass, treble, and MID control based Equalizer is an important circuit in audio amplifier design. Generally, three-stage active Equalizer filters require three control bass, treble, and MID. The bass control allows the low frequency to pass but blocks high frequency and the treble control allows the high frequency to pass
