OPAMP wiht bias current circuit

2-stage CMOS OPAMP design with robust bias

This script-like function implement the design of a 2-stage CMOS OPAMP with a robust bias part (and a MOSFET as resistor in the compensation path), starting from various specifications (e.g. input-referred noise, slow rate, ecc..), as described in J. Mahattanakul & J. Chutichatuporn , Design procedure for two-strage CMOS OPAMP with flexible Noise-Power balacing scheme, IEEE Transactions on Circuits and Systems I, 52:8, 2005, pp.1508-1514.
As output prompt it also provide a netlist, formatted for LTSPICE.
