Integrated low-data-rate sensor networks
IMEC has also developed a fully integrated UWB impulse radio (IR) receiver in UMC’s 0.18µm CMOS technology.
IMEC has also developed a fully integrated UWB impulse radio (IR) receiver in UMC’s 0.18µm CMOS technology. The UWB receiver operates between 3GHz and 5GHz and can process pulses with 500MHz up to 2GHz bandwidth thanks to a variable channel select filter.
IMEC’s receiver front-end is suitable for most IR approaches and very convenient for carrier-based IR (CB-IR) which enables sufficient flexibility in spectrum definition while keeping the system complexity as low as possible. It comprises an LNA and a quadrature down-conversion mixer. The chip’s total current consumption is 16mA, measured on a 1.8V supply at 20MHz clock rate. It demonstrates the potential of IR-UWB for low-data-rate sensor-network applications.
