folded casecode op amp
Folded cascode results are presented in the form of design equations and procedures. Trade-offs among such factors as bandwidth, gain, phase margin, bias currents, signal swing, slew rate, and power are made evident. Closed-form expressions are developed and a sequence of design steps is established. A graphical representation of the relationships among the gain, power, and phase margin for different capacitive loadings is presented to visually illustrate one form of design optimization. The results of SPICE simula- tions are shown to agree very well with the use of our design equations.
