摘要： An integrated circuit includes a plurality of resonant clock domains of a resonant clock network. Each resonant clock domain has at least one clock driver that supplies a portion of clock signal to an associated resonant clock domain. The resonant clock network operates in a resonant mode with inductors connected to pairs of resonant clock domains at boundaries between the resonant clock domains. Each inductor forms an LC circuit with clock load capacitance in the pair of resonant clock domains to which the inductor is connected.

摘要： A clock driver for a resonant clock network includes a delay circuit that receives and supplies a delayed clock signal. A first transistor is coupled to receive a first pulse control signal and supply an output clock node of the clock driver. An asserted edge of the first control signal is responsive to the falling edge of the delayed clock signal. A second transistor is coupled to receive a second control signal and to supply the output clock node of the clock driver. An asserted edge of the second control signal is responsive to a rising edge of the delayed clock signal.

摘要： A clock system of an integrated circuit includes first and second transistors forming a switch that is used when switching the clock system between a resonant mode of operation and a non-resonant mode of operation. An inductor forms a resonant circuit with capacitance of the clock system in resonant mode. The switch receives a clock signal and supplies the clock signal to the inductor when the switch is closed and disconnects the inductor from the clock system when the switch is open. First and second high impedance voltage sources supply respective first and second voltages to the switch and a gate voltage of the first transistor transitions with the clock signal around the first voltage and a gate voltage of the second transistor transitions with the clock signal around the second voltage such that near constant overdrive voltages are maintained for the first and second transistors.

摘要： A signal generator provides a plurality of oscillating signals, whereby each oscillating signal has a different peak voltage and has a predictable and consistent phase relationship with the other oscillating signals. The signal generator includes a plurality of stacked oscillators arranged between two reference voltages, such that each oscillator in the stack generates an oscillating signal having a different peak voltage. Each oscillator stage in a designated oscillator includes a transistor that is connected to a transistor of a corresponding stage in another oscillator. This arrangement of the oscillators provides for charge transfer between the corresponding stages to provide for similar voltage swings in each oscillating signal, as well as to provide for predictable phase relationship between the oscillating signals.

摘要： A sense-amplifier monotizer includes an amplifier circuit and a keeper circuit. The amplifier circuit outputs a predetermined logic state while a clock signal is in a first phase, and samples a data signal and outputs at least one of the data signal and a complementary logic state of the data signal while the clock signal is in a second phase. A subsequent change of the data signal does not affect an output of the amplifier circuit once the data signal is sampled while the clock signal is in the second phase. The keeper circuit keeps a logic state of the sampled data signal once the data signal is sampled while the clock signal is in the second phase. The amplifier circuit may receive multiple data signals, and output a data signal selected by the select signal and/or a complementary value while the clock signal is in the second phase.
