Butler common base oscillator

Touch screens are increasingly popular, yet many developers have never designed one. This guide provides a step-by-step approach to the necessary hardware and software for successful touch screen implementation. Touch screens are ubiquitous in industrial control systems, consumer electronics,...

In this experiment, an oscillator is constructed using an operational amplifier along with several passive components. This specific configuration is known as a Wien Bridge oscillator. The frequency of the oscillator is determined by the resistors R4, R5 and...

This chapter discusses the operation and circuitry of transistor oscillators, which can be categorized into two types: feedback (similar to vacuum tube oscillators) and negative-resistance (current multiplying). Transistor oscillators can generate sine waves using various operational modes, including some...

This document discusses the use of small microcontrollers, such as those from the PIC and Atmel series, which typically operate at 5V and require less than 100mA for complete system functionality. Some PICs can function at lower voltages, such...

A design for a digitally controlled analog oscillator is being developed. The control voltage is generated by a microcontroller (Arduino) and is utilized through two operational amplifiers, along with a resistor and capacitor network that forms an integrator circuit....

The JFET Pierce crystal oscillator accommodates a broad frequency range of crystals without requiring circuit modifications. The JFET gate does not load the crystal, which preserves a high quality factor (Q) and ensures excellent frequency stability. The JFET Pierce oscillator...
