  • Abstract
    A new programmable capacitance scaling scheme based on the utilisation of two tunable operational transconductance amplifiers (OTAs) is presented. The capability of the OTAs allows tunable positive/negative capacitance scaling factors. The scheme has been verified with simulations and experimentally using commercial bipolar OTAs and can be implemented in CMOS technology.
