Op Amp 741 Non Inverting Amplifier Circuit With Simulated Waveform

May 15, 2022 by circuit-admin Leave a Comment

Op Amp 741 Non Inverting Amplifier Circuit

The non-inverting amplifier is one of the most popular op-amp circuits similar to the op-amp inverting amplifier circuit. It provides a gain to the input signal without any change in the polarity. If a sine wave is fed to the input of this op-amp noninverting amplifier, the output will be an amplified sine wave with zero phase shift. Here the input is … [Read more...] about Op Amp 741 Non Inverting Amplifier Circuit With Simulated Waveform

12v Led Battery Level Indicator Circuit (Led Bar Graph)

May 1, 2022 by Charles Clark Leave a Comment

12v Led Battery Level Indicator Circuit

Most often, you may need a lead-acid battery voltage level monitoring circuit. Here is an example; if you use the lead-acid battery for my inverter and so it requires constant voltage charging. But the inverter provides current charging only, so you may use a self-made battery charger circuit that provides a constant 14-volt charging. Charger output should be … [Read more...] about 12v Led Battery Level Indicator Circuit (Led Bar Graph)

IR Transmitter and Receiver Circuit for Best Remote Control System

April 30, 2022 by Charles Clark Leave a Comment

IR Transmitter and Receiver Circuit

A remote control system for appliances makes our life smarter and easier. The wireless remote control circuit may be based on IR waves or RF waves, IR being cheaper. An IR emitter circuit is based on TSOP at the receiver section. Each TSOP operates at a particular frequency which depends on a number present on it. So each TSOP requires a specific remote controller for … [Read more...] about IR Transmitter and Receiver Circuit for Best Remote Control System

Automatic Temperature Controlled Fan Circuit Using Thermistor

April 30, 2022 by Charles Clark Leave a Comment

Automatic Temperature Controlled Fan Circuit

This is a simple automatic temperature-controlled fan circuit using an NTC thermistor. The main components of this temp control fan circuit are a negative temperature coefficient thermistor (NTC) which detects the temperature, a comparator which is used to compare the preset temperature value, and a relay circuit to drive the fan. The power supply … [Read more...] about Automatic Temperature Controlled Fan Circuit Using Thermistor

Binary Phase Shift Keying (BPSK) Modulation Using cd4016 With Simulated Output Waveform

April 24, 2022 by Charles Clark Leave a Comment

Binary Phase Shift Keying

In binary phase-shift keying (BPSK), the phase of a carrier is changed according to the digital pulses signal. BPSK modulator is a phase modulator. Here the transmitted signal is a sinusoid of fixed amplitude. It has one fixed phase when the data is at one level and when the data is at the other level, the phase is shifted by 180 degrees. The binary phase-shift keying method … [Read more...] about Binary Phase Shift Keying (BPSK) Modulation Using cd4016 With Simulated Output Waveform
