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.

摘要： The present invention provides a driver circuitry having a single input terminal for receiving an input signal of binary digits consisting of high and low levels, and at least first and second output terminals, wherein the input signal is varied almost linearly in a first time period so as to be shifted between high and low levels, the driver circuitry comprises first and second control circuits. The first control circuit is coupled to the input terminal for receiving the input signal. The first control circuit is also coupled to the first output terminal for outputting a first output signal of binary digits via the first output terminal. The first control circuit is biased between a high voltage line which supplies a high level of voltage and a low voltage line which supplies a low level of voltage. The first control circuit is adjusted to shift the first output signal between the high and low levels within an initial period of the first time period and then keep the first output signal at the shifted one of the low and high levels until after the first time period expired. The second control circuit is coupled to the input terminal for receiving the input signal. The second control circuit is also coupled to the second output terminal for outputting a second output signal of binary digits via the second output terminal. The second control circuit is biased between the high voltage line and the low voltage line. The second control circuit is adjusted to keep the second output signal at one level of the low and high levels at least until the time approaches the termination of the first time period and then shift the second output signal from the one level to another level within a second time period which is short as the initial period of the first time period.

摘要： An integrated digital circuit includes an oscillation circuit comprising basic gate circuits having the number of stages proportional to the number of gates existing in the critical path of a synchronized circuit network and capable of controlling an oscillating frequency by at least one control signal line. A synchronized circuit network constructed with basic gate circuits capable of controlling the delay time by at least one control signal line operates synchronously by an oscillation signal transfer line. A control circuit controls the oscillation circuit and the synchronized circuit network using the control signal line so that the frequency of signal input from an externally input signal line is equalized with the frequency of signal from the oscillation circuit. Thus, the synchronized circuit network can be always operated at the frequency obtained from the oscillation signal transfer line even though the delay time of the basic gate circuit varied by variations of the device characteristics and the like.

摘要： For improvement in processing speed, a high-speed digital signal processor has a feedback loop from a register which stores the calculating result produced by a Signed Digit (SD) arithmetic unit to one of the input ports of the SD arithmetic unit. The SD arithmetic unit executes an arithmetic operation on an input digital signal and the arithmetic result is formed of both signed digit numbers without the need to convert the calculation result represented by an SD number into a binary number.
