IT is well known that changes in the d.c. characteristics of transistor amplifiers with temperature are particularly severe, and tend to limit the range over which these devices can operate. The d.c.

If you know or can estimate a low-noise amplifier’s gain or noise bandwidth, you can measure the other spec using only a handful of resistors and an ac voltmeter (Reference 1). The method in this ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

Many PIC processors require 5-V power while being programmed, yet battery-powered systems may contain low-voltage devices that will be damaged at voltages above their maximum voltage ratings. In ...
