Abstract :
Improved switched-current bilinear noninverting 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. The ASIZ simulation results show good agreement with the theoretical results.
