Build an adjustable high frequency notch filter: 02/06/03  EDN-Design Ideas / Although you can obtain universal, resistor-programmable switched-capacitor filters that are configurable as notch filters, most cannot operate at bandwidths higher than 100 kHz. Further, the typically 16

Composite Amp Provides High Gain & Bandwidth: 04/28/94 EDN-Design Ideas

Composite Amplifier Boosts Precision Of Programmable Voltage Source: 07/08/02 Electronic Design - Ideas for Design / Engineers often need dc voltage sources with very high precision and good resistive and/or capacitive load-driving capability for industrial applications.

ZL2PD HF RF Signal Generator - This circuit came out of some work I did for the two antenna analyzers which are described elsewhere on this site. Those instruments both include an RF signal generator. This is used as the signal source to drive the impedance bridge and detectors used to measure impedance.

Wideband AGC has 60 DB Dynamic Input Range: 10/10/96 EDN-Design Ideas

Wideband Filter Only Has Two Different Components : 01/21/02 Electronic Design - Ideas for Design / Wideband filters with bandwidths in excess of an octave can be created by cascading a high-pass filter and a low-pass filter. In this design idea, nine-pole high-pass and low-pass filters have been constructed using a modified equal-element design.
