This paper generalizes the concept of the oscillators based on the operational transresistance amplifier (OTRA) into the fractional order domain. The added parameter in the fractional-order design is an important in practical and can model the non-ideality of the conventional capacitors. The general condition and frequency of oscillation have been derived analytically in terms of the circuit components...
A CMOS digitally programmable lossless floating inductor is proposed. The proposed inductor is based on current conveyors and resistor array to provide digital tuning of the inductance value. The presented block realizes a programmable floating inductor tuned from 0.42763 mH to 5.67 mH. As an application for the proposed circuit a resonant circuit and low pass filter have been realized using the digital...
This paper presents two novel Floating Current Source (FCS) based CMOS negative second generation current conveyor (CCII-) realizations suitable for very large scale implementation. The proposed realizations provide high voltage and current tracking accuracy, as well as large voltage and current transfer bandwidths. Simulations show that the first proposed wide band CCII- bandwidth is about 972 MHz...
