Capacitively-coupled multi-domain distributed driver

A method that comprises:

• driving a first bus line with a first set of transistors;
• switching the first set of transistors sequentially using a first set of delay elements;
• driving a second bus line with a second set of transistors;
• switching the second set of transistors sequentially using a second set of delay elements;
• and
• using capacitive coupling between corresponding nodes of the first and second sets of delay elements to synchronize switching of the first and second sets of transistors.

A bus driver that comprises:

• a first current source configured to supply a drive current to a first bus line via a first gating transistor;
• a second current source configured to sink a drive current from a second bus line via a second gating transistor;
• a first buffer that couples a first gate signal from a first node to the first gating transistor;
• a second buffer that couples a second gate signal from a second node to the second gating transistor;
• and
• a capacitance between the first and second nodes to synchronize transitions in the first and second gate signals.
