If channel length modulation is present. what is the overall output impedance of the following CG stage?
  • a)
    Rd || {Rs*(1+gm * ro) + ro}
  • b)
    Rd || {Rs*(1+gm * ro) + 2ro}
  • c)
    Rd || {Rs*(1+gm * ro) – ro}
  • d)
    Rd || {Rs*(2+gm * ro) + ro}
Correct answer is option 'A'. Can you explain this answer?

The impedance looking into the drain of M1 would be similar to that of a CS stage with source degeneration. That implies the impedance is Rs*(1+gm * ro) + ro. But this impedance is parallel to Rd. Hence, the overall output impedance becomes Rd || {Rs*(1+gm* ro) + ro}.
