This page has two unusual two-transistor oscillators. I set the component values for a low frequency application. Both circuits draw only about 1 microamp of current. Materials on the topic Datasheet Fairchild 2N3904 Datasheet Fairchild 2N3906 ...
Tracking down rodentia (or otherwise)-caused cable cuts, and differentiating them from normal open circuits, is critical. Evolving the circuit design for expanded functionality makes it even more valuable. It’s just part of the job. Every ...
The circuit in Figure 1 combines a V BE -referenced current source with a current mirror to implement a simple two-terminal, fully floating LED current sink or source. This approach is well-suited for applications in which tight current accuracy is ...
My recent DI contribution (Another silly simple precision 0/20 mA to 4/20 mA converter, Ref. 1 ) used the LM337 regulator in a novel circuit arrangement to translate an input 0-20 mA current source into a 4-20 mA two-wire transmitter current loop ...
Recently, frequent Design Idea (DI) author Christopher Paul showcased an innovative and high performance true-two-wire current source using a depletion mode MOSFET as the pass device in “A precision, voltage-compliant current source” ( ...
4-Stage Synchronous Bidirectional Counter The AC169 is fully synchronous 4-stage up/down counter. The AC169 is a modulo-16 binary counter. It features a preset capability for programmable operation, carry lookahead for easy cascading and a U/D ...
