Abstract Advances in cosmic microwave background (CMB) science depend on increasing the number of sensitive detectors observing sky. New instruments deploy large arrays superconducting transition-edge sensor (TES) bolometers tiled densely into ever larger focal planes. High multiplexing factors reduce thermal loading cryogenic receivers and simplify their design. We present design focal-plane m...

Built-in self-test (BIST) refers to those testing techniques where additional hardware is added to a design so that testing is accomplished without the aid of external hardware. Usually, a pseudo-random generator is used to apply test vectors to the circuit under test and a data compactor is used to produce a signature. To increase the reliability and yield of embedded memories, many redundancy...

Intercropped corn (Zeu mays L.) and soybean [Glycine mux (L.) Merr.] may produce more total yield per hectare than either grown separately, ie., land equivalent ratio (LER) >l. Low N fertility, limited moisture, and weed competition have each been reported to result in high land equivalent ratios. Thus it was hypothesized that intercropping advantages were greater under stress conditions. The o...

The demand for higher data rates in communication networks raises the need for test equipment operating above 40Gb/s. PRBS generators are commonly used to provide test patterns for highspeed blocks such as MUX or CDR circuits. While generators with pattern lengths of 2-1 have been reported at rates of 100 Gb/s [1], a 2-1 pattern is required for testing CDRs to ensure that phase lock is maintain...

In this paper, we propose new methodology to enhance the QoS in cost and energy efficient WDM/OFDM PON system. In this, the WDM technique supports more number of ONU and the OFDM technique provides high spectral efficiency and flexible sub-channel bandwidth allocation. Here, we have reduce BER at ONU by using the post dispersion compensation technique inorder to reduce the chromatic dispersion ...

We have succeeded in developing three techniques, a precise lens-alignment technique, low-loss built-in Spatial Multiplexing optics and a well-matched electrical connection for high-frequency signals, which are indispensable for realizing compact high-performance TOSAs and ROSAs employing hybrid integration technology. The lens position was controlled to within ±0.3 μm by high-power laser irrad...

In this paper we have find great applicability in RNS implementation for the Diminished-one modulo 2n+1 Adder using Circular Carry Selection (CCS) circuit. This adder presents a modulo addition of different bit values for n = 8, 12, 16, 24, 32, 48, 64. We are using the Diminished-one criteria using Circular Carry Selection (CCS) technique for the proposed modulo adder. The circuit design of pro...
