An oscillator provides a source of repetitive A.C. signal across its output terminals without needing any input (except a D.C. supply). The signal generated by the oscillator is usually of constant amplitude. The wave shape and amplitude are determined by the design of the oscillator circuit and choice of component values. OSCILLATOR BASICS electronics tutorials 5. Choose a device with low flicker noise, this can be reduced by RF feedback. A bipolar transistor with an unby passed emitter resistor of 10 to 30 ohms can improve flicker noise by as much as 40 dB. see emitter degeneration. 6. The output circuits should be isolated from the oscillator circuit and take as little power as possible. Bipolar Transistor Cookbook — Part 5 | Nuts & Volts Magazine The bipolar transistor is the most important “active” circuit element used in modern electronics, and it forms the basis of most linear and digital ICs and op amps, etc. This eight part series focuses on basic transistor theory, characteristics, and presents a wide range of practical bipolar transistor application circuits.
