Combined Light-/Dark-Activated Switch Circuit
Two operational amplifiers are utilized in a bridge circuit configuration to detect high and low light levels. Potentiometer R2 adjusts the dark level, while resistor R1 controls the light level. Resistor R3 is configured so that approximately 1A of the...
Phantom Wah for guitarists
This is an op-amp implementation of a Vox style wah, with the inductor replaced by a gyrator circuit. With the component values given the frequency response is similar to a standard wah. By replacing one of the resistors with a...
Power Function Circuit
It is possible to easily generate various non-linear functions such as X^(1/2), X^2, X^3, 1/X, XY, and X/Y using logarithms. In this context, division is transformed into subtraction, while multiplication is converted into addition.
The application of logarithmic properties in electronic...
Speech amplifier circuit
This circuit can be housed within a box containing a speaker to create a convenient microphone amplifier. It is suitable for use by teachers, guides, lecturers, and others in crowded or noisy environments. The design is based on the audio...
Diamond differential amplifier circuit input
Almost all DC amplifier circuits are utilized as the input stage of differential circuits. Many complementary symmetry circuits also employ a double differential complementary sub-circuit along with a constant current source for the input stage. The constant current source possesses...
