MAX1703 Single-Cell Boost Converter Circuit
When you design a circuit with only a single-cell battery, you will need boost-converter to provide enough voltage for most ...
55MHz Scope Sensitivity Amplifier
Scope sensitivity amplifier is a vital front-end signal processing for every scope instruments. The function of this circuitry is simple: ...
Two-Band Bxandall Active Tone Control
Using active circuit for tone control means that we can provide cut and boost, maintaining overall amplifying factor of original ...
Pulse Width (PWM) Controller Circuit
A LM3900 quad operational amplifier can be used to build a pulse width (PWM) controller. The LM3900 was chosen because ...
Small TV Modulator Using A Motorola MC1374
How can television modulator be small and simple like this? First, it uses integrated circuit, and the second, any TV ...Pulse Width (PWM) Controller Circuit
A LM3900 quad operational amplifier can be used to build a pulse width (PWM) controller. The LM3900 was chosen because it only need single supply voltage of 4 to 30 V. This circuit can give 100 percent pulse-width control. A1 … Continue reading
Two Methods for Push Button Controlled Power Switch
On these two following circuits, we can latch on the SCR (and thereby the lamp) by momentarily closing S1, thereby feeding gate drive to the SC via R1. The gate is tied to the cathode via R2 to improve circuit … Continue reading
Separate ON-OFF Touch Switch
Providing a touch switch can be a cool way to make your circuit looks sophisticated. Moreover, providing separate touch pad for “on” and “off” function improve the safety, since touching one function doesn’t trigger opposite action to what we expect … Continue reading
Remote On-Off Switch through Small Transformer
This is a remote on-off switch circuit. With this circuit, we can take the benefit of using small switch to control larger AC current from high power devices. Safer operation is the other benefit, since this circuit is control the … Continue reading
