  • Patent number: 10566959
    Abstract: A method and a sense amplifier flip-flop (SAFF) for fixing setup time violations in an integrated circuit (IC) design. The SAFF includes a master latch coupled to a slave latch, wherein the master latch includes a sense amplifier and the SAFF is configured with an equal number of p-type metal oxide semiconductor (PMOS) transistors and n-type metal oxide semiconductor (NMOS) transistors to reduce block area of an integrated circuit (IC). The method includes receiving a clock signal, receiving a data signal, applying the data signal to the sense amplifier when the clock signal is at a low level, wherein a portion of the sense amplifier is responsive to the inverted clock signal, storing a value of the data signal in the slave latch when the clock signal transitions from the low level to the high level, and providing an output signal from the slave latch.

  • Publication number: 20200021250
    Abstract: Systems and methods are provided for clocking scheme to reduce nonlinear distortion. An example system may include at least two processing paths, each including at least one circuit exhibiting nonlinear behavior. Nonlinearity may be managed during processing of signals, such as by assessing effects of the nonlinear behavior during the processing of signals, and controlling clocking applied via at least one path based on the assessed effects, to reduce the effects of the nonlinear behavior during the processing of signals, eliminating the need for post-processing corrections. The controlling of clocking may include adjusting timing of a clock applied in the at least path, such as by introducing a timing-delay adjustment to a clock when the clock is applied to a circuit after the circuit exhibiting nonlinear behavior. A timing-advancement may be applied to signals processed via the at least one path, particularly before the circuit exhibiting nonlinear behavior.

  • Publication number: 20190379390
    Abstract: An analog-to-digital convertor circuit converts the output of a loop filter circuit to a digital signal. A random sequence generation circuit generates a random sequence. Adder circuitry adds the random sequence to the digital signal to generate a randomized digital signal. Noise transfer function impulse response detection circuitry processes the randomized digital signal and the random sequence to determine a noise transfer function impulse response. Loop filter configuration circuitry configures the loop filter circuit based on the noise transfer function impulse response. The random sequence generation circuit may comprises a high-pass sigma delta modulator. The noise transfer function impulse response detection circuitry may determine the noise transfer function impulse response, and the loop filter configuration circuitry may configure the loop filter based on the noise transfer function impulse response.

  • Publication number: 20190006388
    Abstract: Inventive concepts describe a method for high performance standard cell design techniques in FinFET based library using LLE. Inventive concepts describe a fabrication process using a standard FinFET cell layout having double diffusion breaks (DDBs) and single diffusion breaks (SDBs). According to one example embodiment, the method comprises of removing one or more fingers of a P-type FinFet (PFET) from a standard FinFET cell layout. After removing the one or more fingers, a Half-Double Diffusion Break (Half-DDB) is introduced on a N-type FinFET (NFET) side inside a cell boundary using a cut-poly layer. The cut-poly layer not only isolates the PFET and NFET gates and also becomes an integral part of hybrid structure. Further, the removed one or more fingers of PFET gates are converted to two floating PFET gates by shorting a drain terminal and a source terminal of the PFET gate to a common power net.
