new design of operational amplifier


Recommended Posts

this attach file is a new design  of....please download it and help me .

please help me in simulation it and highlight the most important features of the design

Design and simulate a two stage CMOS operational amplifier shown in the Fig., for these

  DC Voltage Gain > 60dB
  Unity Gain Bandwidth > 70MHz
  Phase Margin > 50 degrees
  Power Dissipation: as low as possible
  Technology: 2µm
  Power Supply: 3.3V
  Load Capacitance: 2pF
  Output Voltage Swing > 2Vp-p
 Make a unity feedback buffer and check the settling time of the circuit when you inject
a step voltage to the input with rise and fall time of 1µs.
