    摘要: IEEE 1149.1 Test Access Ports (TAPs) may be utilized at both IC and intellectual property core design levels. TAPs serve as serial communication ports for accessing a variety of embedded circuitry within ICs and cores including; IEEE 1149.1 boundary scan circuitry, built in test circuitry, internal scan circuitry, IEEE 1149.4 mixed signal test circuitry, IEEE P5001 in-circuit emulation circuitry, and IEEE P1532 in-system programming circuitry. Selectable access to TAPs within ICs is desirable since in many instances being able to access only the desired TAP(s) leads to improvements in the way testing, emulation, and programming may be performed within an IC. A TAP linking module is described that allows TAPs embedded within an IC to be selectively accessed using 1149.1 instruction scan operations.

    摘要: An embodiment of the invention provides a single-ended polar transmitting circuit. The single-ended polar transmitting circuit comprises a DAC, a differential-to-single-ended converter, a GmC filter and a load. The GmC filter comprises two gain stages, two filters, two switching devices, a translinear loop and a current mirror. When a second clock signal is high, a first current is conducted through the load, a second switching device and a second gain stage. When a first clock signal is high, a second current is conducted through a first switching device and the second gain stage. The first gain stage has a transconductance Gm1 and the second gain stage has a transconductance Gm2. The bandwidth of the GmC filter is approximately equal to the square root of the quantity (Gm1*Gm2)/(C1*C2). The bandwidth of the GmC filter is substantially a constant value.

    摘要: In an apparatus and method for monitoring defects in wafers, a monitoring circuit is fabricated on an area of each one of the wafers. The monitoring circuit includes representative devices that replicate similar devices located in a die area of the wafers. Defects if present in the representative devices contribute to a generation of a noise, thereby causing an imbalance in a differential signal measurable across selected ones of the representative devices. A digitizing circuit that uses a common mode voltage as a reference to measure the imbalance digitizes the differential signal to a digital signal, the digital signal being indicative of the noise generated by the defects. The digital signal is stored over a configurable time interval to form a digital bit stream. The digital bit stream is compared to a reference to determine whether the defeats are within an allowable range.

    摘要: A wide band, wide operating range, general purpose digital phase locked loop (PLL) runs in the digital domain except for the associated Time Digitizer (T2D) and Digitally-Controlled-Oscillator (DCO). By calibrating the T2D and DCO on the fly, a constant PLL loop BW is achieved by using the calibrated Phase Frequency Detection (PFD) and DCO information to normalize the control loop correction regardless of the input clock frequency, power supply voltage, processing and temperature variations. PLL loop BW is completely decoupled from the operating conditions and semiconductor device variation. This means that the PLL loop BW can be chosen very aggressively to reject the noise, thus achieving a low jitter, high performance PLL. Furthermore, since this PLL can reliably operate over a wide operating range, it is a one-design-fits-all general purpose PLL.
