µC makes inexpensive sine-wave generator -  12/17/98 Issue of EDN  You can use A/D converters or external, controllable oscillators to generate sine waves from low-power, low-cost µCs. However, these methods add cost, reduce reliability, increase circuit and software complexity, increase power consumption, and increase overall size. Alternatively....Page includes several designs.  Scroll to find this one.... [Design Idea by Jorge Luis B Romeu, IdeaWorks LTD, Syracuse, NY]
1kHz Sinewave Generator -  Simple circuitry, low distortion, battery operated.  Variable, low impedance output up to 1V RMS.  (electronic circuit added 06/07/08) 
3 phase sinusoidal waveform generator uses PLD -  10/12/06 EDN-Design Ideas....Five ICs substitute for electromechanical three-phase source.... EDN is migrating links. This link is not verified.  Search the "title" EDN for new link.
4 Transistor Tracking Transmitter -  Schematic and parts list only, no circuit description included…. [Tony van Roon's circuit]

68HC11 Synthesizes Accurate Sine Wave -  09/02/96 EDN-Design Ideas....You can use a 68HC11 and a 12-bit serial DAC (Figure 1) to generate accurate sine waves without using floating-point arithmetic. Figure 2 shows a block diagram for this sine-wave generator. You can easily analyze the generator's behavior by writing state equations in the z domain. You can also write equations in the s domain. The location of the two poles.... [Design Idea by Mika Maaspuro, Espoo, Finland]
Adjustable High/Low Frequency Sine wave generator -  ….... [Site is under construction right now]

AF Generator -  My generator can produce sine- and squarewaves with frequencies between 1 Hz and 100 kHz and amplitudes ranging from zero to 1.55 Veff in 600 Ohms. Sinewave distortion is 0.1% or less between 20 Hz and 20 kHz, somewhat greater outside this region. The output voltage …(electroninc design added 04/05/06)
Amplitude-stable oscillator has low-distortion, low-cost -  11/09/00 EDN-Design Ideas....The multivibrator is a common circuit that consists of an amplifier with both positive and negative feedback (Figure 1a).When the output is positive, the positive….PDF contains multiple circuits, scroll to find the one of interest.... [Design Idea by Moshe Gerstenhaber, Chau Tran, and Mark Murphy, Analog Devices Inc,Wilmington, MA]
AN-263: Sine Wave Generation Techniques -  National Semiconductor Application Note  (app note added 2/06)
AN-319: Simple Interface between D/A Converter & Microcomputer Leads to Programmable Sine-Wave Oscillators -  AN-319 Analog Devices Application Notes....[App Note] 
Audio LED VU meter -  Audio level meter circuits are fairly often requested.  The circuit was designed to work with an audio power amplifier which operated off +18v-0v-18v power rails. The actual voltage used is not too critical except that the feedback is referred to the LED chain which itself is anchored to a +12v rail, hence the separate stabilizer for this. It has one large advantage over most of the LED chips available - all the LEDs are in series so it only draws 20mA irrespective of the number of LEDs illuminated....[4QD-TEC: Electronics Circuits Reference Archive]
Basic RF Oscillator #1 -  This basic circuit is eash to build and the components are not critical.  Most of them can be found in your junk parts  box…. [Tony van Roon's circuit]

CMOS hex inverter generates low-distortion sine waves -  9-Jun-05 Issue of EDN  Audio signal source uses hex inverter and handful of passives.... [Design Idea by Al Dutcher, West Deptford, NJ; Edited by Brad Thompson and Fran Granville]
Compensation Extends Oscillator's Range -  12/05/96 EDN-Design Ideas....A simple technique provides phase compensation for the oscillator in Figure 1a. In this circuit, a tungsten lamp regulates the amplitude of a crystal bridge oscillator.  This type of oscillator produces a very low-distortion output at a very stable frequency. The op amp must have a negligible phase shift at the operating frequency, which.... [Design Idea by Israel Schleicher, Green Spin, Bakersfield, CA]
Crystal Filter yields Pure Sine Wave -  06/98 Intersol Application Note # AN9815 / (app note added 6/03)

Current Feedback Amps Square Up Fast Signals -  06/23/94 EDN-Design Ideas....Using current-feedback amplifiers to convert signals from sine waves to square waves for DSP confers advantages over the more common comparator approaches. Current-feedback amplifiers have wide bandwidths and relatively small and constant propagation delays. These small, constant delays help meet the setup-and-hold requirements of....
