Abstract :
The Boyle op-amp macromodel and its variations are the core of op-amp macromodels. Many macromodel parameters are functions of biasing. A new op-amp macromodel is proposed that can monitor biasing conditions and re-adjust the macromodel component values. A comparison is made with simulations and lab measurements for the HA-2720. The HA-2720 is a programmable op-amp where a wide range of performance can be controlled by adjusting the op-amp´s set current
