Circuit for asynchronous reset in current mode logic circuits

摘要

A current mode logic (CML) flip flop includes a first CML latch and a second CML latch. A plurality of pull-up switches are responsive to a reset signal. Outputs of the first and second CML latches are pulled up to a supply voltage through the pull-up switches. The first CML latch includes a first pull-up isolation switch driven by the reset signal for resetting the latch.
