What is a Programmable Unijunction Transistor (PUT)? Simple – it is a three-lead electronic semiconductor device, similar to a unijunction transistor (UJT), except that its behaviour can be controlled ...
If you’re getting started building your own ham radio gear, it’s hard to imagine a more low-tech transmitter than the Mighty Mite, but [Paul Hodges, KA5WPL] took it one step further and rolled his own ...
Two tuners were developed for this receiver. The more sensitive one uses tetrode transistors in the RF amplifier, mixer and oscillator. Its disadvantages lie in a much higher cost and a 12 to 14 db ...
Designers seeking a quick and easy frequency source often use a relaxation oscillator (Fig. 1) based on digital gates such as the 74HC14 inverter with hysteresis. The oscillator is also useful in ...
This file type includes high-resolution graphics and schematics when applicable. 1. Bob Pease built this varactor-input op-amp out of discrete components, based on an old design of Jim Williams. A ...
[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...
A technical paper titled “Gate Drive Circuit Suitable for a GaN Gate Injection Transistor” was published by researchers at Nagoya University. “A GaN gate injection transistor (GIT) has great potential ...
For 65nm and later-generation processes, the advanced memory has achieved fast operation (250MHz) and low active power (148mW) in a 2Mbit test chip TOKYO, September 26, 2005 -- Renesas Technology Corp ...
