The Switched Current (SI) circuit is a circuit technique which is able to realize analog sampled-data circuits with a standard CMOS technology. In this paper, a new switched-current bilinear integrator configuration with greatly improved sensitivity to transistor mismatch is described. The realization of the circuit is based on the modification of the corresponding block diagram, to eliminate the required current inversions without delay. The resulting circuit with a reduced number of current mirrors has improved sensitivity performance to current mirror ratio variations.
