A TTL counter, an 8-channel analog multiplexer, and a 4th-order lowpass filter can generate 1kHz to 25kHz sine waves with a THD better than -80dB (Figure 1). The circuit cascades the two 2nd-order, continuous-time Sallen-Key filters within...

Abstract: A broadband phase-lock loop (PLL) building block integrated circuit (IC) that can accommodate signal frequencies from 0.5GHz to 9GHz is presented. The design integrates a prescaler with selectable divide ratio, a phase detector, ...

Recent advances in semiconductor-process technology and circuit-design techniques have brought down the prices of switched-capacitor filters (SCFs) by a factor of three. As an example, five-pole Butterworth low-pass filters sell for less t...

Abstract: This design idea describes a simple circuit to generate a programmable negative control voltage. It takes the output of a single supply digital-to-analog converter (DAC) and produces a variable negative voltage. The DAC output fr...

Abstract: This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the provision of a minimum duratio...

Abstract: This application note explains 4-20mA current loops and intelligent transmitters and explains their need for high-resolution low-power DACs. An optimum power-supply chip is not the only critical choice to be mad...

Abstract: This application brief describes the techniques used to build and calibrate/compensate new-generation all-silicon delay lines. Both EconOscillators and delay lines use a compensated voltage-controlled delay line (VCDL) scheme to ...

摘要：本文記錄了自1910年以來壓控振蕩器(VCO)的發(fā)展歷史，給出了在RF IC中集成VCO的實(shí)例。文章闡述了相關(guān)技術(shù)，并探討了產(chǎn)品性能、尺寸的演進(jìn)過程。文章還預(yù)測了未來的發(fā)展趨勢...

Abstract: As integrated circuits (ICs) speed up, the rise/fall times of most pulse and function generators (5ns typical) become inadequate for measuring time intervals below 20ns. You can overcome this limitation with analog switches or ad...

The circuit of Figure 1 produces an accurate variable-frequency sine wave for use as a general-purpose reference signal. It includes an 8th-order elliptic, switched-capacitor lowpass filter (IC3) that is clocked with a 100kHz square wave g...

Abstract: A design idea for a white-noise generator is realized and revised. Two low-noise amplifiers (LNAs) in cascade amplify the noise produced by a reverse-biased Zener diode operating in junction-breakdown mode, producing white noise ...
