JFET AC Coupled Integrator

This is JFET AC Coupled Integrator circuit. This circuit is used to achieve very high voltage gain. To achieve very high voltage gain this circuit uses “µ-amp” technique. Here is the circuit : C1 is used as  a capacitance multiplier or Miller integrator. It will allow the circuit to handle very long time constants. [Source: National Semiconductor Application Note]

FSK Demodulator Using LM565

The FSK demodulator is the electronics device that converts the FSK signal to serial digital signal. To transmit digital serial data we use FSK modulation and to get back the digital data at the receiver, we need to demodulate it. Here is the circuit: The main component of this circuit is LM565. For mark /space coding, this demodulator circuit uses […]

Long Distance Video Wire

This circuit is used to connect the camera with very log wire. This is actually a video amplifiers. This circuit consist of two part, they are sender part and receiver part. At the sender part, this circuit uses an amplifier to make a stronger signal. So the signal can be transmitted through the long cables. To transmitted the signal, this […]
