    摘要: A method is provided for forming non-overlapping clock signals 402 and 404 for an integrated circuit. A reference clock 300 whose frequency is twice that of a desired operating frequency for the integrated circuit is used. A master clock signal is formed which has a high pulse width T9a which is approximately the same as the high pulse width of the reference clock, but the frequency of the master clock is one half the frequency of the reference clock. Likewise, a slave clock signal is formed which has a high pulse width T10a which is approximately the same as the high pulse width of the reference clock, but the frequency of the slave clock is also one half the frequency of the reference clock. The high pulse width of either or both the master clock signal and slave clock signal is then widened by an analog delay means, but by an amount T13 and T14 which is less than the low pulse width of the reference clock, so that the master clock signal and the slave clock signal do not overlap each other. As the propagation time of circuit elements within the integrated circuit varies due to changes in operating temperature or voltage, the analog delay T13 and T14 is changed proportionally to compensate for the changes in propagation time of the circuit elements.

    摘要: A variable delay circuit (10) capable of changing delay time includes a latch circuit (13) constituted of a pair of inverters (17,18) cross-coupled to each other and a transistor (16) serving for reducing the voltage difference between the two inputs of the latch circuit (13) based on a control signal (CT) applied thereto. The control signal is also supplied to a pair of transfer gates (14,15) to control the delay time of the variable delay circuit. The latch circuit has two inputs, between which the transistor (16) is coupled, and each of which are coupled to further respective transfer gates' output, at which point a respective buffer (11,12) is coupled to feed the output signals. When the control signal (CT) becomes a high level, the state of the transistor (16) becomes low impedance, so that the voltage difference between the two inputs of the latch circuit (13) is reduced, and so that the state of the latch circuit can be quickly and easily changed with small energy. The variable delay circuit can set a minimum delay time smaller than that of the conventional delay circuit, allowing the variable range of delay time to be greater.

    摘要: A dead-time generating circuit includes a constant current circuit; a current generating circuit generating a capacitor-charge current; and a control circuit receiving a dead time control signal and a comparator signal. The control circuit generates a dead time generating signal based on the dead time control signal and the comparator signal, and a charge/discharge signal based on the dead time generating signal. Charging or discharging of a capacitor is controlled by the capacitor-charge current in accordance with the charge/discharge signal. A voltage of the capacitor is compared with a threshold voltage in order to generate a comparator signal when the voltage of the capacitor exceeds the threshold voltage. The control circuit generates the charge/discharge signal for a duration starting from a time when the delay time has elapsed from the rise or fall timing of the dead time control signal until the control circuit receives the comparator signal.
