- Arthur Edang Maria Lourdes Lacanilao-EdangIn the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued that since the exponential voltage of a ...Jan 26, 2024
- Stephen WoodwardA previous Design Idea “Gated 555 astable hits the ground running” ( Ref. 1 ) offered a fix for the problem of the excessively long first pulse that’s generated by traditional topology 555 astable circuits on start up when gated ...Jan 23, 2024
- Nick CornfordWhile refurbishing an ageing audio mixer, I decided that the level meters needed special attention. Their rather horrible 100 µA edgewise movements had VU-type scales, the drive electronics being just a diode (germanium?) and a resistor. ...Jan 22, 2024
- Stephen WoodwardThe classic and versatile 555 finds its way into many low to moderate frequency oscillator applications. Some of these require the ability to selectively gate oscillation on and off on demand and the 555’s RESET pin can conveniently be used ...Jan 18, 2024
- Stephen WoodwardKeeping op-amp outputs “live” at and below zero volts, generating symmetrical output signals, and processing bipolar analog inputs, are all examples of design situations where a few milliamps of negative voltage rail can be a necessity. ...Jan 10, 2024
- Nick CornfordSecond test circuit I looked at several types of AGC circuits (strictly, Automatic Level Control). JFETs are the usual starting-point but are inherently non-linear and need to be surrounded by lots of stuff to limit the signal voltage across them ...Jan 9, 2024
- Nick CornfordA while ago, I needed (or wanted) a pocket-sized audio sine-wave generator: simple, stable, repeatable, single-gang control pot, 9 V battery-powered. A “squashed tri-wave” approach looked appropriate. While the principle is easy make a ...Jan 8, 2024
- Douglas SudjianThe control circuit in Figure 1 senses a given load and automatically soft-starts the load by synchronously adjusting the power to that load. You can also manually adjust the power delivered to the load by controlling the phase angle of the line ...Jan 1, 2024
- Stephen WoodwardAwhile back I published a simple design idea for a thermal airspeed sensor based on a self-heated Darlington transistor pair ( Ref. 1 ). See Figure 1. Figure 1. Older design idea with self-heated Darlington thermal airflow sensor. In the circuit, ...Dec 29, 2023
- Stephen WoodwardA classic analog application is the full-wave precision rectifier (absolute value) function. Many variations exist on this theme, each with its own supposed (often rather minor and sometimes downright dubious) advantages compared to competing ...Dec 22, 2023
