## 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

## 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

## MOSFETs – Enhancement-Type, Depletion-Type

Two main types of FETs that presently exist are: JFETs and MOSFETs. MOSFETs can be further classified into depletion type and enhancement type. Both these types define the fundamental mode of operation of MOSFETs, while the term MOSFET itself is the abbreviation of metal-oxide-semiconductor-field-effect transistor. Due to the fact that the two types have different … Read moreMOSFETs – Enhancement-Type, Depletion-Type

## P-Channel MOSFET in H-Bridge Applications

Introduction P-channel MOSFETs are usually implemented for load ON/OFF switching. The ease-of-use of P-channel options on the high side allows them to be very convenient for applications like Low-Voltage Drives (H-Bridge Networks) and non-isolated Point of Loads (Buck Converters) and in applications in which space is a critical limitation. The key benefit of a P-channel … Read moreP-Channel MOSFET in H-Bridge Applications
