Abstract
This paper presents static and dynamic studies of a new CMOS realization for the inverting second generation current conveyor circuit (ICCII). The proposed design offers enhanced functionalities compared to ICCII circuits previously presented in the literature. It is characterized by a rail to rail dynamic range with high accuracy, a low parasitic resistor at terminal X (1.6Ω) and low power consumption (0.31mW) with wide current mode (3.32GHz) and voltage mode (3.9GHz) bandwidths.Furthermore, a new MISO current mode bi-quadratic filter based on using ICCII circuits asactive elements is proposed. This filter can realize all standard filter responses without changing the circuit topology. It is characterized by active and passive sensitivities less than unity and an adjustment independently between pole frequency and quality factor. The operating frequency limit of this filter is about 0.8GHz with 0.674mW power consumption.The proposed current conveyor circuits and bi-quadratic filter are tested by TSPICE using CMOS 0.18µm TSMC technology with ±0.8V supply voltage to verify the theoretical results.
