Paper Abstract

This paper describes a circuit implementing 12 fully independent biquad digital filters operating on (Delta) - (Sigma) modulated signals with 28 b resolution. A carry-save adder with partial carry propagation (Delta) -(Sigma) modulator is used together with a pipelined architecture that interleaves all of the filters on a single datapath. Implemented in TSPC logic, the circuit comprises 95 K transistors, including a variable frequency on-chip clock generator.
