The LTE standard supports a maximum throughput of 300MBit/s using 4×4 MIMO and a channel bandwidth of 20 MHz. At the same time the latest HSDPA technology supports 82MBit/s using 2×2 MIMO and Dual Cell techniques. While LTE uses a conflict-free interleaver, which allows highly efficient implementation of parallel decoders for such throughputs, HSDPA uses the UMTS interleaver that causes memory access...
Chip reliability becomes a great threat to the design of future microelectronic systems with the continuation of the progressive downscaling of CMOS technologies. Hence increasing the robustness of chip implementations in terms of error tolerance becomes an important issue. In this paper we present a case study in reliability-aware design tolerating transient errors. A state-of-the-art WiMAX channel...
In this paper, we present a two-stage variable-gain low-noise amplifier (LNA) used in a frequency modulation (FM) radio receiver front-end for a variety of portable audio devices. We also describe a tunable antenna interface and a voltage regulator used in the front-end. The front-end can be tuned to resonate at FM frequencies from 63 to 129 MHz. The two-stage LNA achieves a programmable small-signal...
