摘要： In accordance with at least one embodiment, an improved voltage headroom self-biased receiver is provided. In accordance with at least one embodiment, tail current sources are biased so as to be cross-coupled with respect to each other. In accordance with at least one embodiment, startup control is provided to counter defect-induced current and to ensure the circuit can function properly even with large amounts of defect current. In accordance with at least one embodiment, a positive type (p type) channel metal oxide semiconductor (PMOS) tail current transistor is modulated by a negative type (n type) channel metal oxide semiconductor (NMOS) differential pair virtual negative supply voltage and a NMOS tail current transistor is modulated by a PMOS differential pair virtual positive supply voltage. The amplifier's output common mode is thus self correcting to p type to n type transistor strength differences.

摘要： A phase-locked loop (PLL) system including a phase-frequency detector for generating an up signal or a down signal based on a phase difference between a reference clock and a feedback clock is provided. The PLL system further includes a phase-error spreading circuit for generating phase-spread pulses based on a relationship between a first time attribute of the up signal or the down signal and a second time attribute of the phase-spread pulses. The PLL system further includes a voltage-controlled oscillator (VCO) for generating a VCO clock based on the phase-spread pulses. The PLL system may also include a charge pump that generates a pumping signal based on the phase-spread pulses.

摘要： A conductive line varies in thickness to assist in overcoming RC delays and noise coupling. By varying line thickness, variation in conductor width is avoided if necessary to maintain a specified minimum pitch between conductors while maintaining predetermined desired RC parameters and noise characteristics of the conductive line. Conductor depth variation is achieved by etching a dielectric layer to different thicknesses. A subsequent conductive fill over the dielectric layer and in the differing thicknesses results in a conductive line that varies in thickness. Different conductive line thicknesses available at a particular metal level can additionally be used for semiconductor structures other than a signal or a power supply conductive line, such as a contact, a via or an electrode of a device. The thickness analysis required to determine how interconnect thickness is varied in order to meet a desired design criteria may be automated and provided as a CAD tool.

摘要： A semiconductor (10) has an active device, such as a transistor, with a directly underlying passive device, such as a capacitor (75, 77, 79), that are connected by a via or conductive region (52) and interconnect (68, 99). The via or conductive region (52) contacts a bottom surface of a diffusion or source region (22) of the transistor and contacts a first (75) of the capacitor electrodes. A laterally positioned vertical via (32, 54, 68) and interconnect (99) contacts a second (79) of the capacitor electrodes. A metal interconnect or conductive material (68) may be used as a power plane that saves circuit area by implementing the power plane underneath the transistor rather than adjacent the transistor.
