1.5V liquid crystal display circuit
The Motorola company's MC14440 CMOS integrated circuit is designed for timing and displaying calendar functions. It utilizes a 32.768 kHz NT cutting type quartz crystal along with fine-tune capacitance to generate time-based signals. The display circuit operates on a 1.5...
Cmos Based Vehicle Anti-Theft Alarm
This circuit features automatic exit and entry delays, an optional instant alarm zone, an optional intermittent siren output, and an automatic reset. By adding external relays, the vehicle can be immobilized and the lights can be flashed. The alarm is...
IC4030-4031 Typical Operating Circuit Schematic and Datasheet
The diagram below illustrates a typical operating circuit for the video line driver using the IC4030/4031 schematic. It incorporates the MAX4030E/MAX4031E, which are unity-gain stable operational amplifiers that offer high-speed performance, rail-to-rail outputs, and 15kV ESD protection, as stated in...
Cmos touch switch
This touch switch does not rely on mains hum for switching; it can be used with battery-powered circuits. The Schmitt trigger IC1 forms a 100 kHz oscillator, and IC2a, which is biased into the linear region, amplifies the output and...
Cmos-oscillator
This circuit is guaranteed to oscillate at a frequency of approximately 2.2/(R1 x C) if R2 is greater than R1. Additionally, the number of gates can be reduced further by replacing gates 1 and 2 with a non-inverting gate.
The described...
Precision Full-Wave Rectifier
This circuit utilizes two operational amplifiers (op amps) to generate a full-wave rectified version of the input signal. Op amp IC1 inverts the negative-going signal, but due to diode D2, it remains close to zero. IC2 generates a positive-going signal....
cmos based vehicle anti theft alarm

The car alarm circuit...
3 Band Graphic Equalizer
This simple equalizer utilizes a single operational amplifier (op-amp) and provides three frequency ranges: low frequency, mid frequency, and high frequency. With the specified component values, it achieves approximately ±20 dB of gain or attenuation at frequencies of 50 Hz,...
Capacitive load driver
The circuit utilizes a 100-ohm isolation resistor that allows the amplifier to drive capacitive loads greater than 500 pF. This resistor effectively isolates high-frequency feedback from the load, contributing to circuit stability. Low-frequency feedback is returned to the amplifier's summing...
