CitaciónAlonso Morgado, R. del Río and J. M. de la Rosa: "Design of a 130-nm CMOS Reconfigurable Cascade ΣΔ Modulator for GSM/UMTS/Bluetooth". Proceeding of the 2007 International Symposium on Circuits and Systems (ISCAS), New Orleans, May 2007.
ResumenThis paper reports a 130-nm CMOS programmable cascade ΣΔ modulator for multistandard wireless terminals, covering three standards: GSM, Bluetooth and UMTS. The modulator is reconfigured at both architecture- and circuit level in order to adapt its performance to the different standard specifications with optimized power consumption. The design of the building blocks is based upon a top-down CAD methodology that combines simulation and statistical optimization at different levels of the system hierarchy. Transistor-level simulations show correct operation for all standards, featuring 13-bit, 11.3-bit and 9-bit effective resolution within 200-kHz, 1-MHz and 4-MHz bandwidth, respectively.
