CMOS Toggle Flip Flop Switch
The circuit below uses a CMOS dual D flip flop (CD4013) to toggle a relay or other load with a momentary push button. Several push buttons can be wired in parallel to control the relay from multiple locations. A high...
Cmos oscillator
Adjusting the 100 K ohm potentiometer modifies the discharge rate of capacitor Ct, thereby affecting the output frequency. A square wave output is produced. The maximum frequency achievable with CMOS technology is constrained to 2 MHz.
The circuit described involves a...
CMOS Combination lock
This Electronic Lock circuit is not only simple but it is also very good. It can easily be configured to provide either momentary or continuous output. Key sequences of up to 9 digits are possible. You can pre-enter part of...
CMOS Un-Buffered Inverter based Sine / Square Generator
This circuit is based on the State Variable Band Pass Filter, incorporating amplitude-limited regenerative feedback.
The State Variable Band Pass Filter (SVBPF) is a versatile filter design that allows for simultaneous control over the center frequency, bandwidth, and gain. This filter...
Night security light
This simple circuit is built around a CMOS IC 4060 to obtain the required timing. During daytime, the LDR has low resistance and keeps pin 12 of IC1 high, preventing IC1 from oscillating. When it is dark, the LDR resistance...
A Dozen Small Cmos Alarm Circuits circuit
This document presents a collection of compact, self-contained alarm circuits. These circuits are designed to operate with a very low standby current, making them ideal for battery-powered applications. They can be triggered by both normally-open and normally-closed switches, while some...
frequency doubler with 4011
This frequency doubler utilizes a CMOS quad two-input NAND gate package, specifically the 4011 type. The core of the frequency doubler includes an inverter (IC1B) along with two differentiating networks composed of resistors (R1, R2) and capacitors (C1, C2). The...
Electronic Switch ON-OFF
Here we have three choices, with which we can make electronic switches that use our touch or pressing (push button). We thus exploit the very big resistance of entry, that present the gates CMOS. In the fig.1 we have two...
CMOS Toggle Flip Flop Using Laser Pointer circuit
The IR photo transistor Q1 (Radio Shack 276-145A) or a similar component is connected to the set input (pin 6). It is essential to shield the photo transistor from direct light to ensure that the voltage at the set input...
