    • A method of balancing signal interconnect path delays between an analog domain and a digital domain of an integrated circuit includes applying a test signal to a selected one of a plurality of communication paths between the analog domain and the digital domain. A rising edge delay and a falling edge delay of the test signal is equalized by adjusting a body bias voltage of a delay element configured within the selected communication path. A rising edge delay and a falling edge delay for each of the remaining communication paths is compared with the equalized rising edge delay and falling edge delay of the selected communication path, and a body bias voltage for one or more of a plurality of delay elements configured within each of the remaining communication paths is adjusted until corresponding rising and falling edge delays thereof match the equalized rising edge delay and falling edge delay of the selected communication path.

    • A body-biased enhanced current mirror reference circuit is disclosed wherein the body bias voltage of a current mirror device is varied to adjust its threshold voltage. Both the drain and body potentials of a replica mirror transistor are controlled to selected values. The drain is set to an expected DC voltage output of an NFET current mirror device. The body potential is set to a maximum desired value to prevent forward biasing of the body-to-diffusion junction(s) of one or more current mirror devices, which is accomplished by a feedback control circuit. A low-frequency, low-precision op amp drives the gate of a replica load device so that the body of the replica NFET current mirror device is set to a maximum bias voltage. The maximum bias voltage is also used to bias the body of a diode connected NMOS reference transistor, so that the current in the NFET current mirror device will be approximately equal to the current in the diode-connected NMOS reference. An auxiliary NFET current mirror device may be added to the body-biased enhanced current mirror circuit with the body connected to ground as in the unmodified current mirror to negate a non-monotonicity of the current output.
    • 公开了一种体偏置增强电流镜参考电路,其中电流镜装置的体偏置电压被改变以调节其阈值电压。 复制镜晶体管的漏极和体电位都被控制为选定值。 漏极设置为NFET电流镜器件的预期直流电压输出。 身体电位被设置为最大期望值,以防止由反馈控制电路实现的一个或多个电流镜装置的体对扩散结的正向偏置。 低频,低精度运算放大器驱动复制负载装置的栅极,使得复制NFET电流镜装置的主体被设置为最大偏置电压。 最大偏置电压也用于偏置二极管连接的NMOS参考晶体管的主体,使得NFET电流镜器件中的电流将近似等于连接二极管的NMOS参考电流。 辅助NFET电流镜装置可以被添加到主体偏置的增强电流镜电路中,其中主体连接到地面,如在未修改的电流镜中,以消除电流输出的非单调性。

    • Systems and methods for controlling electro-migration, and reducing the deleterious effects thereof, are disclosed. Embodiments provide for reversal of an applied voltage to an integrated circuit when a measurement indicative of an extent of electro-migration indicates that a healing cycle of operation is warranted. During the healing cycle, circuits of the integrated circuit function normally, but electro-migration effects are reversed. In one embodiment, micro-electro-mechanical switches are provided at a lowest level of metallization to switch the direction of current through the levels of metallization of the integrated circuit. In another embodiment, if the measurement indicative of the extent of electro-migration exceeds a reference level by a specifiable amount, then the voltage applied to the integrated circuit is reversed in polarity to cause current to switch directions to counter electro-migration. A plurality of switches are provided to switch current directions through a lowest level of metallization so that the circuits function normally even though the polarity of the applied voltage has been reversed.

    • A method and apparatus for determining jitter and pulse width from clock signal comparisons provides a low cost and production-integrable mechanism for measuring a clock signal with a reference clock, both of unknown frequency. The measured clock signal is sampled at transitions of a reference clock and the sampled values are collected in a histogram according to a folding of the samples around a timebase which is either swept to detect a minimum jitter for the folded data or is obtained from direct frequency analysis for the sample set. The histogram for the correct estimated period is statistically analyzed to yield the pulse width, which is the difference between the peaks of the probability density function and jitter, which corresponds to width of the density function peaks. Frequency drift is corrected by adjusting the timebase used to fold the data across the sample set.
