It is observed that the Weighted least-square (WLS) technique, including the modifications, results in equiripple error curve. The resultant error as a percent of the ideal value is highly non-uniformly distributed over the range of frequencies for which the differentiator is designed. The present paper proposes a modification to the technique so that the optimization procedure results in lower maximum relative error compared to the ideal values. Simulation results for first order as well as…

Calibration Techniques for Time-Interleaved SAR A/D Converters

New calibration techniques are proposed for time-interleaved SAR ADCs capable of cor- recting the gain, offset and timing mismatches, as well as the static nonlinearities of individ- ual ADC channels stemming from the capacitor mismatches that enable a design of time- interleaved con- verters that use minimum-sized capacitors and operate in the thermal-noise-limited regime for maximum energy and area efficiency.

Eigenfilter design of higher-order digital differentiators

Comparison to the McClellan-Parks algorithm for minimax equiripple filters shows that both are optimal in the sense of different minimum norms of the error function, but much better performance is obtained with the proposed approach in most of the frequency band, except in the narrowband region near the cutoff edge.
