We present a methodology for implementing discrete-time signal processing operations, such as filtering, with molecular reactions. The reactions produce time-varying output quantities of molecules as a function of time-varying input quantities according to a functional specification. This computation is robust and independent of the reaction rates, provided that the rate constants fall within c...

LLCL filters for grid-tied inverters have been adopted to get better performance the harmonics near switching frequency than commonly used LCL filters. However, resonant peak caused by a pair of unstable resonance poles is introduced and makes system become unstable. In this paper, biquad filter composed notch resonator restrain peak. method, point are placed at appointed frequency, transferred...

A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

The design of fractional order inverse Chebyshev low pass filter has been presented in this paper. (1+α) filters have designed by comparing the transfer function notch with second-order filter. Particle swarm optimization utilized to derive coefficients fractional-order varying α from 0.1 0.9. canonical forms these realized using multiple input Biquad circuits. value circuit elements for each d...

This paper presents an electronically tunable current-mode SIMO/MISO universal biquad filter using multi-output current controlled current conveyor transconductance amplifiers (MO-CCCCTAs). The proposed filter employs only two CCCCTAs and two grounded capacitors. The proposed configuration can be used as either single input multi-output (SIMO) or multi (three) input single output (MISO) current...

A digital lossless two-pair terminated at both ends with “passive” multipliers is studied. Conditions for low sensitivity of the transfer-function magnitude with respect to the digital multiplier coefficients are derived. It is shown that low sensitivity property can be achieved by forcing certain “matching” conditions, at the terminations. The application of these results to the understanding ...

The design procedure of low-sensitivity second-and third-order class-4 Sallen and Key active resistance-capacitance (RC) allpole filters, using impedance tapering, has already been published. There a ladder structure in the positive feedback loop of an operational amplifier was used. In this paper desensitization using impedance tapering is applied to class-3 circuits with negative feedback ref...
