Sažetak
In this paper a voltage mode active-RC simulation of a passive ladder RLC filter is investigated in the integrated circuit realization. It is shown that by integration there arises a problem: the parasitic capacitance of integrated resistors in active-RC on-chip filters cause that those filters become unstable and oscillate. On-chip resistors having parasitic capacitances can be described as distributed elements with RC-transmission-line nature. Therefore, we show how to model the on-chip resistors and find the causes of filter instabilities and possible solutions. The simulations are run using PSpice. It is shown that more carefully designed and/or compensated analog filter will be stable and realizable in analog integrated-circuit technology.
