He uses a simple two-transistor multivibrator along with some diodes and capacitors to generate a minimal negative voltage for this purpose. The circuit is simple and only produces a small ...

a very simple op amp circuit with some detail omitted If ... That’s the infinite gain. Any positive or negative output voltage will quickly “hit the rail” or the supply voltage which ...

ROHM has developed a new lineup of high accuracy current sense amps — the BD1423xFVJ-C and the BD1422xG-C. They are qualified ...

Figure 5 Simulation shows how a level-shifting circuit can be used to dynamically adjust a negative output voltage. Using a simple circuit to enable an adjustable negative output voltage can work with ...

The presented circuits are simple and do not need complicated redesign or adjustment ... D2 producing the positive output voltage +V1 and one diode producing the negative output voltage -V3. The ...

Why on earth would a simple digital clock circuit need a negative 1.5V ... no sound (there's no alarm function) would need a negative voltage supply. What is that -1.5V doing, and if it IS ...
