Voltage controlled oscillator circuit using LM566 VCO IC

Voltage controlled oscillator circuit is an electronic oscillator circuit whose output frequency is controlled by an input voltage source. By varying the input voltage, we can change the output frequency. A voltage controlled oscillator can produce frequencies ranging from few Hertz to tens of Gigahertz. Voltage to frequency converters is used in frequency modulation FM […]

Inverting amplifier (OPAMPs)

The inverting amplifier is one of the types of closed loop opamp configuration. In this configuration, the non-inverting (+ve) terminal of the opamp is connected to the ground, while the inverting terminal acts as input terminal. Negative feedback is present between the output terminal and (-ve) inverting terminal of OPAMP. Importance of negative feedback in Inverting […]
