Cosmic Circuits rolls WiMO AFE platform
Designed and silicon-tested on the Fujitsu 90nm Low-Leakage process technology, the analogue front end brings several features that make it friendly to system-on-chips. Utilising innovative analogue circuit technology suited to nanometer technology nodes, and a digital-friendly architecture that uses minimum number of amplifiers, Cosmic Circuits has achieved a very low die-area solution, for single and multi- channel MIMO configurations.
The AFE platform consists of a dual matched ADC (IQ-ADC), dual matched DAC (IQ-DAC), an auxiliary ADC and DAC for monitoring and control, and a versatile PLL, suitable for portable mobile applications. At low power levels for the receive channel, and with a fast wake-up from standby, it helps extend battery life in portable applications.
Commenting on the solution, Ganapathy Subramaniam, CEO of Cosmic Circuits said, "Our WiMO AFE platform is optimised for WiFi and WiMax MIMO applications with low die-area, low-power and flexibility. Its inherent digital-friendly architecture uses minimum number of amplifiers even for large MIMO configurations. We offer silicon characterisation support and customisation for MIMO and single-channel applications."
Combined with the Power-ON-SoC power-regulator portfolio from Cosmic Circuits, a complete analogue solution that addresses both the power-path and signal-path requirements of wireless customers is a reality now..
