Use of the Silicon Resistor in the d.c. Stabilization of Transistor Circuits

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.

Program a PIC Processor In-Circuit Using a 3.3-V Supply

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 ...
