A switching voltage regulator circuit shown in the schematic diagram here can be a low cost solution for your high efficiency requirement electronic circuit design. Unlike other switching regulator circuit that uses special purpose integrated circuit (IC), this circuit uses a standard linear regulator LM317 IC. LM317 regulator IC provide a stable internal voltage reference, and provide the adjustment method. […]

A positive variable voltage reference circuit is shown in the schematic diagram below. A voltage reference can be made using a zener diode, but this method produce a fix reference value. To make a variable reference, we can amplify the fix voltage reference using active components (op-amp or transistors). Here is the schematic diagram of the circuit: This voltage reference […]

This is a schematic diagram of a three-phase pulse generator circuit. This circuit produce 3 phase overlapped output similar with 3 phase AC powerline, you can say this circuit produce the DC pulse version. This schematic diagram shows two CMOS inverters and CMOS 4-bit shift register as the circuit’s main components. The shift register is configured as divide-by-6 Johnson counter, […]

This is a circuit of High-Q Notch Filter. This circuit consist of LM102 and a twin “T” network. Twin T network sum two signal from different path with different phase shift. At certain frequency, the phase shift will be 180 degrees. The sum will produce zero output since one signal is the inverse of other signal, in other words, the […]
