CIRCUIT WITH PARALLEL FUNCTIONAL CIRCUITS WITH MULTI-PHASE CONTROL INPUTS |
摘要 |
A circuit has a plurality of functional circuits (100a-f), each with multiphase control inputs. A control circuit drives the inputs for each phase in parallel. The control circuit (120a-c) comprises a chain of one-shot circuits (120a-c), each comprising a bi-stable circuit (121 ). The bi-stable circuit (121 ) of a first one-shot circuit in the chain has a set input coupled to the basic control signal input (126), the bi-stable circuits (121 ) of a remaining or each remaining one-shot circuit (120a-c) in the chain have a set input output of its predecessor in the chain. Each bi-stable circuit (121 ) has an output coupled to a respective one of the multiphase control outputs (14a-c) and a reset input coupled to the respective one of the multiphase control outputs (14a-c). Loading of the multiphase control outputs (14a-c) by the functional circuits results in a delay of the reset. Thus the pulse durations of the one shot circuits are adapted to the number of functional circuits to ensure sufficient signal development. |
