BJT Differential Amplifier
İki transistörün çalıştığını varsayalım
A MOS differential pair is operated at a bias current of 0,8 . Find V_ov , g_m , r_o , and A_diff using transistors with a WL ratio of 100,
a) Find the differential gain, the common mode gain, and the common-mode rejection ratio if the output is taken single endedly. Assume devices are perfectly matched.
b) Repeat a for differential output.
c) Repeat b when the resistances have a mismatch of 1%.
