Diode Rectification: Half-Wave, Full-Wave, PIV

Updated:

In this post we will analyze diode rectification process and other properties through time-varying functions like sine wave and square wave. Meaning, through voltages and currents which change their magnitude and polarity with respect to time. We will consider the diode to be an ideal diode by ignoring whether it’s a silicon diode or a … Read moreDiode Rectification: Half-Wave, Full-Wave, PIV

Comparator Circuits – Using IC 741, IC 311, IC 339

Updated:

The basic function of a comparator circuit is to accept a linear voltage input and produce a digital output, giving a quick information regarding which one input has higher potential than the second. Difference Between a Comparator and Op Amp The IC 741 is an ideal example of a single op amp, and the IC … Read moreComparator Circuits – Using IC 741, IC 311, IC 339

Digital-to-Analog (DAC), Analog-to-Digital (ADC) Converters Explained

Updated:

In this article we comprehensively discuss how digital to analog, and analog to digital converter circuits work, using diagrams and formulas. In electronics we may find voltages and currents varying continuously with different ranges and magnitudes. 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) counterpart works … Read moreDigital-to-Analog (DAC), Analog-to-Digital (ADC) Converters Explained

Understanding MOSFET Turn-ON Process

Updated:

While designing MOSFET based circuits you might have wondered what is the correct way of turning ON a MOSFET? Or simply what is the minimum voltage that should be applied across gate/source of the device to switch it ON perfectly? Although for many digital systems this might not be an issue, 5V systems such as … Read moreUnderstanding MOSFET Turn-ON Process
