Filter design, be it active, passive, or switched capacitor, is traditionally a mathematically intensive pursuit. There are many architectures and design methods to choose from. Two methods of high ...

When multistage designs are intended using low power op amps, the load presented by a poorly designed stage might in fact impair the intended signal frequency response above the high pass corner. Some ...

An integrated, low-power state variable filter that consumes less than 3 µA can be implemented to achieve multiple design objectives using only three of the four available op amps on a single ...
