Op-Amp Symbol Terminals

  • Basically op-amp symbol is triangle shape how the current flow through op-amp
  • op-amp basically have 8 pins we use only five pins
    1. pin number 2 is the inverting terminal
    2. pin number 3 is non-inverting terminal
    3. pin number 4 is negative -15 volt input
    4. pin number 6 is the ouput singal pin
    5. pin number 7 is the +15 volt input
  • When the input is applie to pin no:-2 that is inverting terminal, her the input and otput phase different between 180*
  • When the input is applied to the pin:-3 thet is non-inverting terminal, Here there no phase difference between input and output
  • op-amp has dual supply that is DC supply pin no:- positive supply 7 and negative supply 4. The voltage is applie +15v and -15v
  • the dual supply are same voltage
  • when the two voltage is same is clled balanced dual supply
  • When the dual voltage is not same is called Unbalanced dual supply

Miller Crystal Oscillator Miller Crystal Oscillator Similar to modifications in Colpitt's oscillator, the Hartley oscillator circuit can be modified, to get Miller crystal Oscillator In Hartley oscillator circuit, two inductors and one capacitor is required in the tank circuit. One inductor is replaced by the crystal which acts as an inductor for the frequencies slightly greater then the series resonant frequency. The tuned circuit of L1 and C is offtuned to behave as an inductor i.e. L1. The crystal behaves as other inductance L2 between base and ground. the Internal capacitance of the transistor acts as a capacitor required to fullfill the elements of the tank circuit The crystal decides the operating frequency of the oscillator.

Electronic oscillator division types and use Electronic oscillator division types and use Introduction to oscillator An oscillator is a amplifier and it is a close loop circuit or network. It uses the Positive feedback. It is not require the externel signel and generate the a desired frequency A oscillatpr acts like generator, It oscillates the constant amplitude and frequency. Oscillator can generate the frequency upto gigahertz. Classification of the Oscillators Oscillators are classified based on the type of waveforms generate from the oscillator, range, frequency, parameters used. Based on Output waveforms. Based on circuit components. Range of operating frequency. Based on feedback uses or not uses Types of oscillatprs LC Oscillator Har...
