Abstract
This paper presents the design of a high-performance dual-band wireless capacitive pressure sensor operating in harsh environment. The proposed design is composed of an absolute capacitive pressure sensor, pressure controlled oscillator (PCO), class-E power amplifier (PA) and an antenna. The sensor node collects and transmits the pressure variation in the term of frequency output wirelessly to a nearby base station. Simulation results show that the low frequency band can be tuned from 2. 1 to 2. 6 GHz while the high frequency band ranging from 4. 6 to 5. 1 GHz in a pressure range from 5 to 10 MPa with total output power from 16 to 14 dBm at 0. 35µm CMOS technology.
