Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:

1kHz Sinewave Generator -  Simple circuitry, low distortion, battery operated.  Variable, low impedance output up to 1V RMS.  (electronic circuit added 06/07/08) 
2.4MHz White LED Step-Up Converters with Built-In Schottky in ThinSOT -  Linear Technology Switching Regulator (app note added 6/06)
Audio Test Oscillator -  As a piece of test equipment, an audio oscillator has to be considered essential for anyone working in with hi-fi gear. Toger with an audio millivoltmeter (as described in Project 16), and even better if you have access to an oscilloscope, you will be able to make proper measurements on everything from preamps, RIAA equalization stages (for vinyl disks), tone controls,....(added 4/02)
Few Extra Components Stabilize Oscillator -  02/15/96 EDN-Design Ideas....The circuit beneath the dashed line in Figure 1 is the well-known Wien-bridge oscillator. The lamp is a common tungsten incandescent bulb.... EDN is migrating links. This link is not verified.  Search the "title" EDN for new link.
LT3465A-2.4MHz White LED Step-Up Converters with Built-In Schottky in ThinSOT -  Linear Technology Switching Regulator (app note added 6/06)

Programmable oscillator uses digital potentiometers -  7-Mar-02 Issue of EDN  Digital potentiometers are versatile devices; you can use them in many filtering and waveform-generation applications.  This Design Idea describes an oscillator in which setting the resistance of two digital potentiometers independently programs the oscillation amplitude and frequency. Figure 1 shows a typical diode-stabilized Wien-bridge oscillator that generates accurate sine waves fro.... [Design Idea by Alan Li, Analog Devices, San Jose, CA]
Q Multiplication in the Wien Bridge Oscillator -  by Ramon Vargas 8-11-04
The Wien bridge oscillator is reborn -  13-Jun-02 Issue of EDN  In 1940, William Hewlett and David Packard launched a product from a garage. The product was a Wien-bridge oscillator. It consisted of a single-pole highpass filter in series with a single-pole lowpass filter. To keep the gain constant, the circuit used an incandescent pilot light to provide AGC (automatic gain control].... [Design Idea by Michael Fisch, Agere Systems, Longmont, CO]
Two Transistor Wein Bridge Oscillator -  Scroll Down to find this circuits.  Here is a two-transistor Wien bridge oscillator using an ordinary night-light bulb for stabilization. The output is about 6 volts p-p and can drive fixed loads as low as 2 or 3 thousand ohms without additional buffering. A 10 k amplitude potentiometer….(added 05/05/05)
Wien Bridge Oscillator - This circuit produces an extremely low distortion sine-wave, in spite of the non-linear devices used for amplitude limiting (D1 and D2). The reason is first that distortion (harmonics) are fed to the minus input of the opamp with far less loss than to the plus input, severely attenuating them. Second, a Wien bridge oscillator requires a gain of exactly 3.00. No more and no less. For lowest distortion, calculate the minimum and maximum available gain to just above and just below 3.00. In other words, use as little amplitude control as possible. [Designed by Andrew R. Morris]
Wien Bridge Oscillator is Reborn -  06/13/02 EDN-Design Ideas....In1940, William Hewlett and David Packard launched a product from a garage. product was a Wien-bridge oscillator. It consisted of a single-pole highpass filter in series with a single-pole lowpass filter.... [Design Idea by Michael Fisch, Agere Systems, Longmont, CO]
Wien Bridge Oscillator keeps THD BeLow One PPM -  11/10/94 EDN-Design Ideas....The Wien-bridge sine-wave oscillator uses a light bulb to stabilize its amplitude. The circuit doesn't have a light bulb; it sports several enhancements that lower its distortion.... [Design Idea by Jeff Smith, Analog Devices, Wilmington, MA]

Wien Bridge Theremin -  (circuit / schematic added 2/03)
Wien-Bridge oscillator has simplified frequency control -  In this article, a modified version of the classical circuit that uses a single low-cost variable resistor for frequency control will be described. (electronic design added 05/06/07) [Design by Ramon Vargas 20-8-04]
