Design and realization of a two-stage microring ladder filter in silicon-on-insulator.

چکیده
We report the design and experimental realization of a new type of microring filters consisting of two parallel-cascaded microring doublets connected by a π-phase shift element. Interference between the two second-order microring stages gave rise to a fourth-order filter response with flat-top passband and a bandwidth of 100 GHz. The result demonstrates the feasibility of realizing advanced integrated optics filters based on parallel cascades of high-order microring networks.

In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-Q switched capacitor pseudo 2-path filter. The filter is a sixth–order Chebyshev band-pass filter operating at sampling frequency of 1MHz and center frequency of 250 kHz with a quality factor of 50. The proposed filter has both low-voltage and high speed properties of the auto zeroed integrators ...
