Abstract
A keeper based switch driver can generate overlapping differential signals and increase a crossing point of the overlapping differential signals a first predetermined amount. Additionally, the keeper based switch driver can further increase the crossing point of the overlapping differential signals a second predetermined amount and limit signal swing to an absolute value of a drain-source voltage. A microprocessor can also be electrically connected to a DAC cell with keeper based switch driver through a performance detection circuit. The microprocessor can be configured to receive information from a performance detection circuit and control a current of a variable current source in a keeper bias circuit accordingly.
