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.

Use Wideband Op Amps In Single-Supply Applications:  04/12/04 Electronic Design - Design Briefs /  Most wideband op amps are easiest to use with split supplies. But they can be effectively employed in single-supply circuits.

Wide-Band Analog White-Noise Generator:  11/03/97 Electronic Design - Ideas for Design / Commercially available white noise generators are rather expensive. The circuit presented here, however, is an inexpensive version that produces frequencies up to about 300 MHz. Its operation is based on the noise generated by the Zener breakdown.

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.

Wideband OpAmp Capable of MicroPower Operation :  National Semiconductor Application Notes,24-Oct-2001

Analog input circuit serves any microcontroller:  12/20/2001 EDN - Design Ideas / The simple ADC in Figure 1 is perfect for getting analog signals into a purely digital microcontroller. Using just five surface-mount parts, you can assemble it for less than 50 cents (1000), which is approximately half the cost of a single-chip-ADC approach in the same volume. Moreover, this design takes only one pin from the microcontroller to operate.
