Wenzel Associates Technical Library

Since 1978, Wenzel Associates has defined the state-of-the-art in ultra-low phase noise while providing system manufactures with the highest quality, cost effective frequency components and instruments.

Wenzel Associates introduced the Blue Tops system building blocks to offer oscillator users well-characterized, low noise components, which improved the time to market for new frequency based systems.

Wenzel Associates Technical Library
  • Time and Frequency Circuits and Articles including frequency synthesis and conversion.
  • Crystal Oscillator Tutorial Articles cover oscillator types, terminology, and selection.
  • Spreadsheets/ Programs to calculate pll response, phase noise under vibration, and others

Phase Noise Measurement

Wenzel Associates Technical Library

"The measurement technique compares the phase of an oscillator under test to a reference oscillator with similar or superior noise performance."

The Dice Game on 6802 Nano computer

SB-Projects - San Bergmans

A pair of dice is the first small example application I present here. The interface is nothing more than 2 sets of 7 LED's, arranged in the form of two dice. One push button per die completes the interface circuit

Wide-Bandwidth Dual JFET Opamp LF353

These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage.

They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents.
