intrinsic and n-type) structure is mostly used for constructing the photodiode instead of p-n (p-type and n-type) junction structure because PIN structure provide fast response time. PIN photodiodes are mostly used in high-speed applications. ...
Switching Diodes are a type of semiconductor diode. They are specially designed and manufactured for "on" and "off" on a circuit. As the name suggests, it refers to a diode with a switching function. How to use a Diode as a Switch?
These amplifiers can operate in a heterodyne system. To make this work, the IF coming from mixer 18 must be stable. To accomplish this, a varactor diode 113 is employed to up-convert the frequency. The circuit also includes an f bandpass filter 59 and a low-pass filter 69. Lastly, an...
The Altium Designer circuit simulator is used for engineering analysis and verification of electrical circuits based on SPICE technology. According to this technology, each element of an electric circuit is represented in the form of a mathematical model, where the set of mathematical models of ...
capacitor in the tank circuit. A varactor diode is a type of semiconductor diode whose capacitance across the junction can be varied by varying the voltage across the junction. Thus by varying the voltage across the varicap diode in the tank circuit, the output frequency of the VCO can be ...
Schottky diodes are used in logic circuits. Types of Diodes The various types of diodes are as follows: Zener diode Avalanche diode Photodiode Light Emitting Diode Laser diode Tunnel diode Schottky diode Varactor diode P-N junction diode
The substrate is laid on one inside surface of an 'L' cross section base (40) which carries on its remaining face a variable capacity diode (50) or varactor, e.g. a Schottky diode, a decoupling capacitance (7) to earth and a second decoupling capacitor (9). Both capacitors are in ...
The greater the reverse voltage, the smaller the capacitance. This makes the diode act as avariable capacitor. Some diodes are specially manufactured to serve this function. Their capacitances fluctuate rapidly along with pulsating dc. They are calledvaractor diodes or simply varactors. ...
The demodulator is an essential part of the receiver. It does the reverse function as that of the modulator. The original telegraph signal is separated from the carrier signal by the demodulator circuit. Amplifier The amplifier is used to amplify the power level of the signal to a sufficient ...
