Schottky Diodes

Schottky barrier diodes are semiconductor diodes designed with minimal forward voltage and fast switching speeds which may be as low as 10 ns. These are manufactured in current ranges of 500 mA to 5 amps and up to 40 V. Due to these features they become specifically suitable in low voltage, high frequency applications such … Read moreSchottky Diodes

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

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

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

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

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

Transfer Characteristics

We know that for a bipolar junction transistor (BJT), the output collector current IC and the control input base current IB are related by the parameter beta, which is assumed to be constant for an analysis. Referring to the equation below, we find a linear relationship existing between IC and IB. If we make the … Read moreTransfer Characteristics
