Free electronic circuit design and schematic diagram
Astable multivibrator or oscillator circuit is based on positive feedback. We can design such circuit using op-amp, logic gates, or transistors. Here we can rely on single capacitor capacitor and resistor for the feedback inside op-amp like transistor circuit, which works over wide range of temperature, voltages and transistor gains. The stability is pretty good, for supply voltage changes between […]

Below is a schematic diagram of blocking monostable circuit. The normal state of the transistor is off because the 10 k resistor has been removed. The conduction will be started using a positive pulse at node “a” and the transformer will do the rest. The transistor will again be turned off (by a hefty negative pulse to the base) after […]
Read moreThe monostable flip flop is a electronic circuits that is used to produce a single pulse each time it is triggered. Sometimes, this circuit called a ‘one shoot’. This circuit is very useful, for example it can used to produce a delay for timing applications or debounce a mechanical switch so that only one rising and one falling edge occurs […]
