“…The second design is the active single balanced mixer. The third approach to design CMOS active balanced mixer is using the Gilbert cell multiplier which provides high-quality port-to-port isolation due to its fully differential structure which cancels both LO-RF and IF-RF feedback [23][24][25]. For this reason, the third approach of active double balanced mixer is chosen in this work.…”

In this paper a new design of Ultra-Wide Band (UWB) generator is presented. This circuit is the most important block in multi-bands transmitter architecture of UWB communication system. The proposed UWB generator is composed of multi-bands voltage controlled oscillator (VCO), mixer and rectangular pulse generator which consist of ring oscillator, time delay and AND gate function. The UWB generator is based on multiplying the rectangular pulse envelope to a continuous sinusoidal wave in order to generate the UWB signal. This UWB generator circuit produces an output signal which is characterized by the bandwidth of 1600 MHz divided into three sub-bands of 528 MHz, centered at frequencies of 3.432, 3.96, 4.488 GHz and the limited Power Spectral Density (PSD) is -41.44 dBm/MHz. The maximum amplitude of UWB signal is 214 mV, the pulse is during of 3 ns and the pulse repetition period (PRP) is 32 ns. The power consumption is approximately equal to 26 mW at a voltage supply of 2.5 V. This topology is designed in CMOS 0.35 lm AMS process technology.

“…Zero-IF receiver has the characteristics of small size, low cost and easy-to-monolithic integration. It is a highly competitive structure in RF receiver, and it is attracted much attention in the wireless communication [1][2][3] . But there are following important problems: LO leakage, even-order distortion, DC offset and flicker noise [4] .…”

This paper presents principles of a down-converted mixer for four sub-harmonic and proposes a particle swarm optimization algorithm as a global search algorithm, and the performance equation is used as the assessment of the mixer circuit optimization method. Dielectric substrate adopts Electronic Materials with RF/Duroid 5880 whose dielectric constant is 2.20 and 5mil in thickness. The optimization algorithm can quickly get optimal results. The simulation results show that this mixer achieves higher 1 dB compression point, loss of frequency conversion which is less than 15 dB and good linearity.
