History of Allied Electronics –

1928: Allied Radio was established as the radio parts distribution arm of Columbia Radio Corporation. The company was soon to become one of the most recognizable names in the electronics industry.

1995: Allied is the first electronics distribution company to come out with a CD-ROM catalog and quickly followed-up by entering the e-commerce arena with the launch of a web site.

Cadence Tutorial for VLSI Design

This site contains a complete on-line tutorial for a typical bottom-up design flow using CADENCE Custom IC Design Tools (version 97A). The examples were generated using the HP 0.6 um CMOS14TB process technology files, prepared at North Carolina State University (NCSU) and made available through MOSIS.

Dual-Low-Noise JFET Opamp TL072 TI

The JFET-input operational amplifiers in the TL07x series are designed as low-noise versions of the TL08x series amplifiers with low input bias and offset currents and fast slew rate.

LF398 – Monolithic Sample and Hold Circuit

The LF198, LF298, LF398 are monolithic sample-and-hold circuits which utilize BI-FET technology to obtain ultra-high dc accuracy with fast acquisition of signal and low droop rate. Operating as a unity gain follower, dc gain accuracy is 0.002% typical and acquisition time is as low as 6 µs to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth. Input offset adjust is accomplished with a single pin, and does not degrade input offset drift.

LF398 - Monolithic Sample and Hold Circuit

The wide bandwidth allows the LF198 to be included inside the feedback loop of 1 MHz op amps without having stability problems. Input impedance of 1010Ohm allows high source impedances to be used without degrading accuracy.

LF398 – Monolithic Sample and Hold Circuit

P-channel junction FET’s are combined with bipolar devices in the output amplifier to give droop rates as low as 5 mV/min with a 1 µF hold capacitor. The JFET’s have much lower noise than MOS devices used in previous designs and do not exhibit high temperature instabilities. The overall design guarantees no feed-through from input to output in the hold mode, even for input signals equal to the supply voltages.
