Electronic Circuit

A crystal oscillator is an electronic circuit that actuate the mechanical resonance of a vibrating crystal of piezoelectric material to originate an electrical signal with a very specific frequency. Operation of a Crystal Oscillator A crystal i... Read >

Role of Pass Devices in Low Dropout Linear Voltage Regulators

Which type of pass device is chosen has a major influence on almost all major regulator performance issues. Most notable among these is the dropout voltage, VMIN. It can be seen that the all NPN pass devices of columns A and B have the attributes of a ... Read >

Advancement in Phase Locked Dielectric Resonator Oscillators

Phase Locked Dielectric Resonator Oscillators (PDROs) are widely used in both commercial and military applications. PDROs offer low cost, small size, low noise, efficient power consumption and high reliability required for local oscillator generation in c... Read >

LIGHT CRYSTAL OVER SILICON

LCOS (Light Crystal Over Silicon) is a technology used in display systems. LCOS combines with two ideas: - LCD (Liquid Crystal Display) and DLP (Digital Light Processing) displays. LCD uses liquid crystals, one for each pixel, on glass panels. Ligh... Read >

Circular Connector

Circular connectors: Circular connectors are shaped in circular form and used primarily for external interfacing. A connector will either be male type (with pins) or female type (with sockets) . A male connector includes pins that plug into a socket or si... Read >

Crystal Oscillator

A crystal oscillator is an electronic circuit that produces electrical oscillations at a particular designed frequency determined by the physical characteristics of one or more crystals, generally of quartz, positioned in the circuit feedback loop. Crys... Read >

Load Break Switch

In power applications, switches perform function to energize or unenergized an electric load. On the high end of the scale are load-break switches and disconnecting switches in power systems at the highest voltages (several hundred thousand volts). Lo... Read >

Use of LED and Photodiode in Pulse Oximetry

Pulse-oximetry technology was available in 1930's it became easily available only in the 1980's with advances in the Light Emitting Diode (LED), microprocessors, optical plethysmography and spectro-photometry. Today pulse-oximetry provides a simple, non-i... Read >

CROSSTALK IN ELECTRONICS

Disturbance, caused by electromagnetic interference, along a circuit or a cable pair. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel, to another. In telecommunicati... Read >
