| Popis: | Trabajo presentado al 23rd DCIS celebrado en grenoble del 12 al 14 de noviembre de 2008. This paper presents a fully differential 8th order transconductor-based active complex filter with 2.4MHz bandwidth and centered at 2.5MHz, designed in a 90nm 2.5V 7M and MIM capacitors CMOS process technology. The filter compliants with the requirements of the IEEE802.15.4 standard. Simulation results including mismatching and process variations over the extracted view of the circuit are shown. The filter has a nominal gain of 12dB, good selectivity (20dB@2MHz offset), high image rejection (51dB nominal) and low power consumption (3.6mA @2.5V). This work has been founded in part by the EC through the project A109-Medea+ WITNESS (Wireless technologies for small area networks with embedded security and safety), the Spanish Regional Government of Junta de Andalucía under project TIC-927 and the Spanish Government under project TEC2007-68072. |
