  Our speaker is Naveen K. Yanduru, (Texas Instruments Inc), and the topic of his presentation is   "Achieving highly integrated, re-configurable RF front-ends in deep sub-micron CMOS with an example of a WCDMA, GSM/GPRS/EDGE receiver front-end without inter-stage SAW filter in 90nm CMOS"

Various RF bands, standards, modulation schemes, duplex mechanisms and signal bandwidths needed for the mobile terminal call for a highly adaptable and reconfigurable RF receiver. The biggest bottleneck in achieving this goal lies with the RF pre-select filter at the antenna, which is band specific and creates a bottleneck in being able to share the hardware. Solving this multi band programmability is the biggest challenge in achieving a RF Receiver for software defined radio. A few of the possible architectures and their limitations are presented. However, designing a multi mode RF receiver for a given RF band with highly reconfigurable performance is an achievable goal. A WCDMA/EDGE receiver without inter-stage SAW filter in 90nm digital CMOS is used as an example in illustrating the architecture, circuit and system considerations for such a receiver.

Naveen Yanduru is currently a Design Manager at Texas Instruments Inc., and a Member Grade Technical Staff. While at Texas Instruments he has led design teams in the design of various RF receivers including GSM/EDGE, WCDMA, TDSCDMA, GPS and multi-mode receivers. He is currently involved in the design of DRP/^/TM/ / chips, which are highly integrated ICs in deep sub-micron CMOS processes for mobile phones.
