In an IC 4047 astable oscillator circuit, the output of the IC continuously generates a switching ON/OFF signal. Since the output is never in a stable state and constantly switches between and low and high, it is called an astable multivibrator. The astable ON/OFF switching frequency is adjustable and can be varied by changing the […]

Understanding CMOS IC 4035 Datasheet – 4-Bit Parallel In Parallel Out Shift Register
So now we are talking about this digital IC called 4035 which is made using CMOS technology, that means it will use very low current and will give us high noise immunity. Inside this IC we have got 4 flip-flops which are arranged in such a way that they can hold and shift 4-bit data. […]
2 Simple Voltage to Frequency Converter Circuits Explained
A voltage to frequency converter circuit converts a proportionately varying input voltage int a proportionately varying output frequency. The first design is using the IC VFC32 which is an advanced voltage to frequency converter device from BURR-BROWN specifically designed to produce an extremely proportional frequency response to the fed input voltage for a given voltage […]

10 Easy Op-amp Oscillator Circuit Diagrams Explained
In an op amp oscillator circuit, an op amp is configured with a resistor-capacitor feedback loop or a inductor-capacitor feedback loop, which triggers the op amp to go into an oscillating mode, generating a switching ON/OFF pulses from its output pin. The high-gain and wide passband of operational amplifier (op amp) ICs makes it possible […]
