“…However, even higher operating frequencies can be achieved with recently reported CFOA designs, such as that in [16] which has a 3-dB bandwidth of 110 MHz. By adding a voltage buffer to the CCCII given in [17], [18], CFOA's that are suitable for telecommunication applications can be obtained. We note that another CFOA-based implementation of Chua's circuit has been reported recently [19].…”

“…Looking for a higher degree of control of the design characteristics, the translinear loop based configuration seems to be the most suitable configuration [1,2]. Since their introduction, it has shown the best high frequency performances [3,4]. However, the problem of designing a high performance integrated CCII circuit seems to be still open, especially in CMOS technology [1] where the high frequency response of current mode circuits is greatly improved.…”

In this paper, we propose an improved translinear based CCII configuration. Heuristic algorithm is used for optimal sizing regarding static and dynamic performances. PSPICE simulations for AMS 0.35 µm CMOS technology show that the current and voltage bandwidths are respectively 2.6 GHz and 3.9 GHz, and the parasitic resistance at port X (R X ) has a value of 18 for a control current of 100 µA. The improved configuration is used as a building block into high frequency design applications: a current controlled oscillator and a tunable fully integrable band pass filter. The oscillator frequency can be tuned in the range of [290-475 MHz] by a simple variation of a DC current. The central frequency of the band pass filter can be varied in the range of [1.22-1.56 GHz] and the quality factor vary in the range [8-306] with a simple variation of a DC current.

In this paper, a novel adaptive tuning system used in Gm-C continuous time (CT) filters has been presented. The novelty of this method is the generation of quasi-gradient functions for the adaptive algorithm. By this method we have implemented the fully adaptive tuning algorithm on chip, and received more than 95% precision for the all characteristics of Gm-C filter. All the circuit level simulations and prototype fabrication have been done using 0.6 l CMOS technology of AMS.
