This paper presents a technique of designing OTA using genetic algorithm, obtaining an OTA of 26dB gain and 27MHz bandwidth consuming a power of 426 uwatt. Also GA used to synthesis desired filters on the designed FPAA with design parameters used as a cost function and different trails is done on the FPAA system level which maps the transistor level of the(More)
This paper presents a low power Field programmable Analog Array (FPAA) based on operational transconductance amplifier (OTA) implemented in 90nm 1.2V CMOS technology achieving an operating frequency of 288MHz. Different continuous time filters in a frequency range from 52MHz to 282MHz can be implemented on that FPAA design achieving a max power of 62 mWatt(More)
This paper presents characterization for coupling capacitance in through silicon Vias (TSV) arrays. Two scenarios are proposed to estimate the coupling capacitance between TSVs in TSVs array. First scenario is by using a closed form expression that accounts for the shielding effect resulted by TSVs. Second scenario is based on the existence of initial(More)
