An Impulse based ultra-wide band (UWB) transceiver was designed using 130nm CMOS technology for a Bio-ranging system to improve the quality of cardiopulmonary resuscitation (CPR). It is developed to measure the depth of chest compression in CPR which is crucial factor for CPR quality using IR-UWB technology. The transmitter is composed of impulse generator and power amplifier (PA) operating at the...
In this paper, a Ka-band transmitter/receiver (T/R) front-end for a phased-array radar is proposed. The transceiver includes a receiver channel and a transmitter channel. A function link shared with the receiver channel and the transmitter channel is comprised of a 5-bit phase shifter and a variable gain amplifying circuit including an attenuator and a low noise amplifier. Connection to either the...
A 3-stream, 802.11n WLAN MIMO transceiver, with fully integrated PAs and LNAs in both 2.4GHz and 5GHz bands, and a T/R switch in the 2.4GHz band, was implemented in a standard 90nm CMOS technology. The transmitter achieves an EVM of -28dB at output power of 19dBm and 17dBm in the 2.4GHz and 5GHz bands, respectively. The transmitter power consumption per Mb of data, in 3-stream mode, is 3.7mW/Mb and...
This paper propose a multi-standard transceiver architecture, based on 3.6-to-4.4 GHz UWB impulse transmitter and 402-to-405 MHz super-regenerative receiver for medical implant devices. This architecture eliminates the requirement of frequency synthesizer and power amplifier at transmitter side and LNA, mixers, IF amplifiers and ADCs. at receiver side of implant transceiver. The multi-standard external...
This letter presents a low power and low cost RF transceiver for Zigbee standard (IEEE 802.15.4) using a switchless front-end configuration. It is enabled by designing the matching networks that a low noise amplifier and a power amplifier can share. The transceiver has been implemented in 1P6M 0.18 μm CMOS process. The receiver achieves 4.4 dB NF, -6.5 dBm IIP3 and 25.7 dB gain with 3-step digital...
This paper describes a dual band low-IF transceiver front-end for the Mobile WiMAX (802.16e) standard. The transceiver is implemented in TSMC 0.18 mum CMOS technology and covers the frequency ranges from 2.3 - 2.7 GHz. The front end transmitter provides an output gain control of 50 dB with an EVM below 3%, where as the receiver achieves gain of 37 dB and a noise figure of 3.7 dB. The components included...
A 60GHz Doppler radar for short-range presence detection applications in the unlicensed 60GHz band is described. The 1.1times2.1 mm2 SiGe:C BiCMOS IC includes a 60GHz VCO, a polyphase filter for quadrature signal generation, a low-noise amplifier with current reuse quadrature down-conversion mixer and a power amplifier. The VCO can be tuned from 59.5-61.5GHz. The receiver quadrature accuracy is better...
