Drive circuit detecting slow signal transition |
摘要 |
A drive circuit includes first and second circuit sections. The first circuit section maintains, during an initial stage of a transient period of an input signal, its output level before the signal transition and supplies after the transient period an output signal responsive to the signal transition. The second circuit section has a first circuit portion receiving the input signal and a second circuit portion, responsive to the input signal, and the output of the first circuit section, to accelerate the signal transition of the first circuit portion. Signal delay in a signal transition due to a large parasitic capacitance and resistance can be recovered by the drive circuit. The drive circuit has a large noise margin and operates at a high-speed and in a wide frequency range.
