A 610-mW zero-overhead class-G full-rate ADSL CO line driver.

A 610-mW zero-overhead class-G full-rate ADSL CO line driver.

With the drive to increase the number of ports that can be incorporated onto a single linecard in an ADSL Central Office (CO), and the consequent power consumption and thermal management issues that this increased density raises, power dissipation is a key parameter in the design of an ADSL modem. T...
