5. CMOS Operational Amplifiers - IMS
Analog Design for CMOS VLSI Systems Franco Maloberti Output voltage swing: It is the swing of the output node without generating a defined amount of harmonic distortion. Equivalent input noise: The noise performances can be described in terms of an equivalent voltage source at the input of the op-amp. Typically vn = 40 ÷ 50 nV/ Hz at 1 kHz,
