  1. Since its invention over a half-century ago by Hanz Camenzind at Signetics, the familiar 555 analog timer (in league with its updated pin-compatible CMOS descendants) has become an iconic design element incorporated into useful standardized ...

  2. More than a half-century old, the ubiquitous and mind-bogglingly useful 555 analog timer has become a perennial object for both kudus and criticism. Most of the former and some of the latter is justified, but sometimes a supposed shortcoming will ...

  1. Many applications call for wide-range-tunable LC oscillators that can deliver a nearly constant-frequency, nearly harmonic-free output even when the circuit's output load changes. From a design viewpoint, eliminating either inductive or ...

  2. A free-running generator built on the standard configuration of the 555 timer can't provide a duty cycle of exactly 50%. That's a well-known fact. Fortunately, there are several ways to get around this problem. The best is to place an extra ...

    This project originated from the need to produce a linear crystal-controlled ramp signal for an HP 8620C RF sweep oscillator. It is inspired by a previously published ramp generator design [ 1 ]. That design though suffered from two issues: it used ...

  2. By using JFETs in unusual configurations, you can design simple, high-frequency LC oscillators with few passive components. The structure for implementing the amplifier stage comprises a JFET transistor that you configure as a common drain (Figure ...

  3. Designing astable circuits using the industry-standard 555 timer is a straightforward process when duty cycles are 50% or greater. However, you must overcome the many pitfalls of low-duty-cycle circuits to arrive at a desired result. Using only ...

  4. Electronic Design Proper component selection can help reduce startup time for gated oscillators. Gated oscillators always present the typical problem of having a delay when a digital input control signal enables its oscillation. This delay happens ...
