Gm-C Filter Synthesis Based on LC Prototypes
Two main problems are encountered when high frequency integrated analog filters are to be synthesized: the limitations of the operational amplifiers and the properties of the integrated resistor. The gain of the operational amplifier strongly depends on the frequency so deteriorating the properties of the overall system.
