ABSTRACT:
A circuit is provided having a secondary semi-analog FIR filter connected to a primary filter via a coefficient to reduce the size of the sizes of the resistors used in the primary filter. The coefficient may be one or more intermediate resistors connected between separate resistor/voltage driver banks that make up the FIR filter. The result is a circuit that takes up less chip space required to accommodate the required resistance for a digital to analog converter (DAC). The invention configures the resistor structure to produce the same output result as a conventional circuit, but with smaller resistor values that take up less surface area on the chip.
