A symmetrical, 10 mV peak to peak triangle waveform can be generated by the circuit depicted in the following schematic diagram. This circuit is featured with alternative DC biased output which can be used to feed an ADC. The DC level input offsets the triangle waveform over the input range of the ADC.

This schematic diagram shows an automatic headlight dimmer circuit for your car’s headlight, keep you safe in the dark with maximum bright for farthest visibility, but will automatically switch from high to low beam when traffic approach to save others sight. With Q1 in moderate darkness the variable resistor must be adjusted to generate no base current through Q2. This […]

555 IC is very popular component for timer circuit. With integrator circuit, we can extend the timing period of 555IC timer with reasonable capacitor size. With conventional 555IC timer configuration, the timing capacitor will be large compared to integrator version. You can see the comparison in the graph below the schematic diagram.

The following schematic diagram shown a conventional which is modified to become a VCO (voltage-controlled oscillator) circuit. By replacing the conventional fixed capacitor with a variable capacitance diode (varactor), we can turn a 74S124 multivibrator into a wide-band VCO. High speed logic 74S series is used here to enable this circuit for high frequency operation. Here is the schematic diagram […]
