Abstract
A method and apparatus for reducing bipolar current effects in dynamic logic circuits that are fabricated using the SOI technology is disclosed. A dynamic logic circuit capable of reducing bipolar current effects includes a precharge transistor (or a discharge transistor), a pass transistor, a functional logic circuit block, and an inverter. Connected in series with the precharge transistor, the functional logic circuit block, which includes multiple transistors, receives signal inputs. The pass transistor, connected in parallel with the precharge transistor, receives an identical input as one of the many transistors within the functional logic circuit block. The inverter, connected to a node between the precharge transistor and the functional logic circuit block, provides an output for the dynamic logic circuit.
