Said, L. A., A. H. Madian, M. H. Ismail, and A. M. Soliman, "Digitally Programmable Lossless Floating Inductor Realization using Current Differential Amplifier (CDA)", Proc. of the 16th IEEE Mediterranean Electrotechnical Conference (MELECON 2012), Medina Yasmine Hammamet, Tunisia, March, 2012. Abstract

A digitally programmable lossless floating inductor realization circuit is proposed. The proposed block uses current differential amplifier as an active block and the programmability is achieved through array of capacitors each one is connected to a switch, according to the logic 1 or 0 applied to the switch gate; the array size change and the programmability is achieved. The presented circuit realizes a tunable floating inductor tuned from L=26.624μH to 38.088mH. To show the reliability of the proposed block, Programmable resonant circuit has been implemented using the proposed circuit from frequency 51 kHz to 86 kHz. Also, Programmable low pass filter have been realized using the digital programmable block from frequency 6MHz to 17MHz. The simulation results has been demonstrated and discussed using PSPICE simulation for 0.18 μ m CMOS technology provided by TSMC. The proposed circuit uses ±1.5 V dual supply voltages.

Ismail, "A simplification in integral frequency offset estimation based on joint detection algorithm for WiMAX 802.16e", Proc. of the 26th National Radio Science Conference, (NRSC 2009) , Cairo, Egypt, March, 2009. Abstract

Initial downlink synchronization for orthogonal frequency division multiple access (OFDMA) network access involves timing and frequency synchronization. The frequency offset is produced by oscillator drifts and time-varying Doppler shifts. In mobile WiMAX 802.16e carrier frequency offset (CFO) can be divided into: integral carrier frequency offset (ICFO) and fractional carrier frequency offset (FCFO). There are mainly three methods for CFO estimation: data-aided method, blind and semi-blind. This paper is based on the semi-blind method presented in ldquoJoint detection of integral carrier frequency offset and preamble index in OFDMA WiMAX downlink synchronizationrdquo, IEEE, 2007, see [2]. We simplify the algorithm presented in that paper by (a) using an adder-subtractor instead of using squares to estimate power and (b) by using a XNOR instead of complex multiplier; thereby reducing hardware gates by a factor of 676. Simulation results show only a slight degradation in performance with a considerable reduction in complexity.
