This 20+ GHz VCO uses 0.25microns 3-V CMOS process with thick metal inductor level and high resistivity substrate. The measured center frequency ranges from 21 to 23 GHz.
A radix-4 logMAP turbo decoder for high-speed 3G mobile data terminals is described.
Presently the British Post Office orders and install 24-circuit pulse-code-modulation systems in large quantities for the junction network.
A 5-b flash ADC with a closed-loop THA is implemented in 0.18-mum SiGe BiCMOS.
A 256 bit GaAs SRAM has been designed that incorporates laser programming to allow any defective row or column to be replaced with a spare row or column.
This paper describes a silicon receiver for a multiple-input multiple-output (MIMO) wireless channel that supports up to 28.8 Mb/s using a 4x4 QPSK configuration over a 5 MHz frequency selective ch
We describe a receiver for HSDPA supporting up to 28.8 Mbps using QPSK over a 5 MHz frequency selective 4x4 MIMO wireless channel (5.76 bits/s/Hz).
