Abstract:
An apparatus including a strobed latch circuit with reduced signal propagation time, comprising:first and second bias nodes configured to receive first and second bias voltage potentials;a regenerative latch circuit, coupled between said first and second bias nodes, which includesan associated regenerative voltage level between said first and second bias voltage potentials,a reset state with an associated reset voltage level which is between said regenerative voltage level and said second bias voltage potential and which is closer to said regenerative voltage level than to said second bias voltage potential, andan active state in which said regenerative latch circuit is configured to receive a differential analog signal which includes first and second analog signal phases and in accordance therewith provide a differential digital signal which is latched when one of said first and second analog signal phases transcends said regenerative voltage level; anda reset control circuit, coupled to said regenerative latch circuit and said first and second bias nodes, configured to receive a reset activation signal and in accordance therewith force said regenerative latch circuit into said reset state;wherein said regenerative latch circuit and said reset control circuit together conduct a substantially constant current via said first and second bias nodes during said reset and active states of said regenerative latch circuit.
