    Project Details


    In the design of low power high frequency microelectronic circuits in current mode technology a great research activity in translating conventional voltage mode active RC-filters into the current domain has been reported. One of the promising structures are the classical Sallen-Key family of filters which applies a low-gain voltage amplifier. Low-gain amplifiers may be constructed from particularly simple transistor circuitry. The classical design of the Sallen-Key family of filters, however, suffer from poor parameter sensitivity making it difficult to implement the structure in the high-Q case. In this project a new design strategy is investigated making it possible to obtain sensitivities for the Sallen-Key filters as low as the sensitivities which may be obtained by translating LC-filters into active RC-filters.
