Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Abstract: This paper presents simulation models of filters with operational amplifiers that can be used in digital simulators. It describes the real number modeling used for analog functionally, ...

The integrator power is further reduced by sharing an op amp in the two integrators in each stage and periodically changing the op amp bias condition between a high-current and a low-current mode ...
