An ultra-wideband Voltage Controlled Oscillator (VCO) is presented in this paper. The circuit achieves fast startups and stops which allow wideband pulses to be generated. In addition, the VCO allows bipolar modulations as Binary Phase Shift Keying to be implemented without the need of a shaping circuit as a mixer. The proposed VCO has been integrated on a silicon area of 0.003mm2 in a 65nm CMOS technology...
A single chip CMOS 130 nm transceiver for UWB-IR communications was assembled and measured for further integration into a demonstrator aiming compatibility with the recently published IEEE802.15.6 standard for Body Area Networks. The transmitter achieves a 10.9 mA current consumption for the 15.6MHz pulse repetition frequency and 1.5V peak-to-peak voltage. The receiver is an innovative combination...
The design of an UWB pulse generator is presented. The pulse generator is based on an elementary pulse combination technique which enables the emitted pulse to be precisely shaped. This technique is implemented with no inductor or passive network and can be used to ensure regulation compliance. This generator has been fully integrated in a 0.13 μm CMOS standard technology. Its area is 0.06mm2 only...
This paper presents an analysis of the power consumption of the UWB PHY layer of the IEEE 802.15.4a standard. This work focuses on the transmitter PHY layer implementation. The influence of the different modes settings on the power consumption is investigated. The considered implementations use an FPGA coupled with an UWB pulse generator implemented in an ASIC. The first PHY layer implementation is...
The design of a remotely UHF powered UWB transmitter is presented in 0.13µm CMOS standard process. Power harvesting unit is based on a Dickson voltage multiplier and UWB pulse generator uses filtered combined edge method. Multi-Vt technique and CMOS logic allows pulse generator power consumption between two consecutive pulses to be reduced enough to be remotely powered. It achieves FCC compliant pulses...
The design of a fully tunable pulse generator using only logic cells is presented and simulated with 0.13µm standard CMOS process. The generator is based on the elementary pulse combination and can synthesize different UWB pulse shapes. The generator uses logic gates to achieve the elementary pulses and a H-bridge to make the combination which leads to a zero DC power consumption. To achieve FCC compliant...
The design of an UWB pulse generator is presented in the context of low cost applications. The pulse generator is fully integrated in a 0.13 mum CMOS technology and achieves 1 Vpp magnitude pulses with only 2.25 pJ of energy consumed by pulse and 1.2 V voltage supply. The generation method used in this design is well suited for packaged IC using wire bond interconnections. Tow methods of interconnection...
In this paper, an Impulse Radio (IR) UWB transceiver system design is presented. The presented circuit includes a bipolar pulse generator based on on-chip filter impulse response, and a LNA coupled with high-speed 1-bit digitizer. The presented study is based on several elementary block realizations (LNA, VCO, RF-filter) on a 0.13 um CMOS standard technology. The impact over the characteristics of...
