Abstract

This research aims to design, simulate, build and characterize two topologies transmitters reconfigurable circuits, Impulse Radio Ultra-WideBand (UWB-IR) in process 130 nm CMOS technology types. Currently, most of the transmitters circuits use two types of control to adjust the pulse in the FCC mask. One is control of the frequency inverter using series circuits and the other is the amplitude control circuit with Charge Pump. For new topologies reconfigurable transmitter proposed in this research project intend to add another control, in another words, control of the quantity of pulses in the waveform of the output signal, thus allowing three types of controls. These new topologies are implemented with the following characteristics: bandwidth of 3.1 to 10.6 GHz; power limit -41dbm / MHz (according to the Federal Communications Commission, FCC of the United States); pulse generators type Edge combiner to generate waveform Pseudo Raised Cosine (PRC) variable amounts of pulses; frequency controls and amplitude; Pulse Repetition Frequency (PRF) of 100MHz; Modulation Binary Phase Shift Keying- (BPSK) (only for data transmission). The first transmitter topology will be implemented for use in Micro Impulse Radar (MIR) Phased-array type containing four transmitters modules. This circuit with multiple antennas enables the radiation pattern can be directed electronically without the need for any mechanical rotation. Also, it allows a higher transmission power signal as compared to a transmission technology that makes use of a single antenna. The second transmitter topology is implemented for transmission of data at high rates, but only using a broadband antenna. This topology is implemented in two versions, namely one with passive balun circuit (planar transformer) and the other with active balun (transistors). To elaborate this project, we will use ADS software / Momentum / Keysight for extracting electric models of inductors, transformers and baluns liabilities. For electrical simulation and layout we will use all CAD software tools IC Nanometer Mentor Graphics, together with the design-kit supplied by foundry UMC130nm and manufacturing will use a concept "Fabless" in multi-project wafer template (MPW) called Mini @sic of EUROPRACTICE. Finally, after manufacturing will use Vector Network Analyser-VNA's Microelectronics Laboratory of the Polytechnic School of USP. (AU)
