This paper is concerned with the problem of designing fractional-order time-delay systems with closedloop eigenvalues in a prescribed region of stability. The main idea is to convert the fractional-order systems with time-delays into an equivalent fractional-order systems without delays. At the first, we compute a state Feedback matrix which assigns all the eigenvalues to zero, then by using the method based on similarity transformation and assign the eigenvalues to fractional-order systems without delays compute state Feedback matrix in a sector of the complex plane. This method is achieved by implementing properties of vector companion forms. The proposed algorithm can be used for the placement of closedloop eigenvalues in a specified sector in plane and can be employed for fractional-order linear systems with large-scale. Also, the considerations can be easily extended for two-dimensional (2D) and descriptor fractional-order systems. Also, simulation results are presented to demonstrate the effectiveness of the proposed method.

High gain Balun-low-noise-amplifier (LNA) is proposed for tuner of digital televisions (DTVs). The proposed Balun-LNA is based on CS-CG (common-source-common-gate) structure. To improve the isolasion and frequency response, Balun-LNA has cascode transistors before load resistors. Balun-LNA uses current-bleeding circuit to increasie transconductance of CS transistor, so that current-bleeding transistor has transconductance of N-1 times larger than transconductance of cascode transistor. Thereby, transconductance and current of CS transistor are increased N times, as N-1 times of current pass to current-bleeding transistor. Therefore current of CG and CS stages stay identical. Also, Balun-LNA employs a positive Feedback to satisfy input impedance matching and CG transistor has higher transconductance. By increasing transconductance of CS and CG transistors, the proposed Balun-LNA achieves to high voltage gain. Accordingly, CG and CS tansistors have symmetrical currents and loads at the differential output of the proposed Balun-LNA. Symmetrical loads cause the balanced differential outputs. This proposed Balun-LNA is designed in 90-nm CMOS technology and covers the frequency range of 40 MHz to 1GHz. This Balun-LNA achieves the voltage gain of 22.6 dB, S11 of less than -10 dB and the Minimum NF of 5 dB. This Balun-LNA operates at the nominal supply voltage of 2.2v.
