FET Based Phase Shift Oscillator
Assistance is required for the design of a FET-based Wien bridge oscillator and its simulation using PSpice. Any suggestions would be appreciated.
The Wien bridge oscillator is a type of electronic oscillator that generates sine waves. It employs a bridge circuit...
Stabilized-capacitance-buffer
Q1 and Q2 form a simple, high-speed FET input buffer. Q1 operates as a source follower, while Q2 serves as a current source load that sets the drain-source channel current. The LT1010 buffer provides the necessary output drive capability for...
Electronic Horn
Electronic horn circuit diagram. When the power line is switched on, a basic tone is produced by transistor T2 and transformer X1, which is frequency-modulated by a wandering voltage generator affected by a low-frequency square wave generator. This is a...
Simple Alarm Circuit
The simple circuit generates an audible alarm notification, functioning as a burglar alarm utilizing five transistors.
This circuit operates as a basic burglar alarm system designed to emit an audible sound when triggered. The core component of the circuit is a...
Micro Inverter by 2N6121
This micro inverter is a small-sized device that modifies energy from a battery, producing an output voltage of approximately 220V AC at 50Hz. The circuit comprises two transistors that function as a pulse oscillator or square wave generator, driving a...
Preamp Mixer Stomp-Box for Dobro Guitar
A stomp-box was designed and built for Grammy-winning resophonic guitar player Stacy Phillips. He typically uses two transducers on his Dobro-style instruments: a piezo element mounted internally and a gooseneck-mounted electret microphone positioned approximately one inch above the resonator cover....
led How do I amplify a dc voltage that is too weak to trigger the base in a transistor
The goal is to take the voltage output from a 3.5mm audio jack and use it to light up an LED based on the audio voltage levels. The left audio channel will be connected to the base of a 2222N...
simple microphone preamplifier
The circuit is a simple one-transistor amplifier with an amplification factor of approximately 30-40 dB, which varies depending on the transistor, temperature, and voltage. The dynamic microphone input is a straightforward one-transistor amplifier circuit with no special features. LED D1...
Active Plug Classic
A FET impedance converter is designed for use with the Fishman pickup on a Kay orchestra bass. The circuit is divided into two sections, allowing the input section to be mounted inside the head shell of a 1/4" plug, placing...
