Low-power transceiver design for mobile wireless chemical biological sensors

The design of a smart integrated chemical sensor system that will enhance sensor performance and compatibility to Ad hoc network architecture remains a challenge. This work involves the design of a Transceiver for a mobile chemical sensor. The transceiver design integrates all building blocks on-chip, including a low-noise amplifier with an input-matching network, a Voltage Controlled Oscillator with injection locking, Gilbert cell mixers, and a Class E Power amplifier making it as a single-chip transceiver. This proposed low power 2GHz transceiver has been designed in TSMC 0.35~lm CMOS process using Cadence electronic design automation tools. Post layout HSPICE simulation indicates that Design meets the separation of noise levels by 52dB and 42dB in transmitter and receiver respectively with power consumption of 56 mW and 38 mW in transmit and receive mode
