LOS ANGELES -- Cognet Microsystems Inc. here said it is sampling a CMOS transimpedance amp with 10-Gbit/second speeds. The device uses a special cascaded amplifier structure to achieve high speeds in a standard CMOS foundry process.
Cognet, a mixed-signal communication IC startup, showed some of its first 2.5/3.125-Gbit CMOS products at the National Fiber Optic Engineers Conference in Denver last week.
The CN10KRT chip will feature a full dc-to-9-GHz bandwidth, but dissipates 60 mW from a 1.8-volt supply. K. Joseph Sikias, the company's director of sales and marketing, said that the transimpedance amp represents the first in a series of devices Cognet will offer to move the bulk of the 10-Gbit transceiver chain into CMOS.
