The maximum output voltage from U1 will be Vcc2 in this circuit. ![]() This charges up the capacitor C1 and the inverter toggles its output back to low state.īy doing this Inverter will be operated in its linear region. The output of inverter goes to high state, this is fed back to input. ![]() With the feedback resistor R1 connecting from output to input, it feeds portion of output to input. This is what we are exactly going to do in this circuit, use external components with it to get desired signal of fixed frequency. When electric charge current is applied, it produces vibration in predefined frequency which in turn can be derived as steady waveform using external components connected to it. This property is used to build quartz crystals where Quartz sheets are placed with electrodes connected to it.
