Abstract:
1. A current mode logic digital circuit comprising: a load coupled between a power supply node and at least one output node; a logic circuit component coupled to said output node and having at least one data input node, said logic circuit component comprising a first circuit module and a second circuit module; a first tail current source coupled to said first circuit module; a second tail current source coupled to said second circuit module; a first switch coupled between said power supply node and said first tail current source in a first circuit path parallel to the circuit path containing the load and the first circuit module; and a second switch coupled between said power supply node and said second tail current source in a second circuit path parallel to the circuit path containing the load and the second circuit module; wherein said first switch is triggered to deactivate said first circuit module when said second circuit module is operating and said second switch is triggered to deactivate said second circuit module when said first circuit module is operating.
