摘要： Traditionally, low-noise amplifiers or LNAs have been used in high frequency applications, but for very high frequency ranges (i.e., 60 GHz), building an LNA to meet performance needs has been difficult. Here, however, an LNA has been provided that operates well around 60 GHz. In particularly, this LNA is generally unconditionally stable, has a generally low noise factor or NF, and has a generally high gain around 60 GHz.

摘要： An array update operation which specifies number of (row-identifier, value) pairs for updating rows in a table of a database is implemented as follows. A block-identifier of a block (on disk) that holds a row identified by a row-identifier in a specified pair is looked up using a database index, and the block-identifier thus found is stored in a structure. Use of a row-identifier to look up the corresponding block-identifier, and the storage of the block-identifier in the structure are repeatedly performed, for each of several specified pairs. Next, a vector read is performed, to read and store in a cache, each block identified by a block-identifier in the structure, and all the blocks that have been read are stored in the cache during a single function call. Thereafter, rows identified in specified pairs are modified, in blocks currently in the cache, using the values in the specified pairs.

摘要： One embodiment of an apparatus for cancelling supply noise includes an input circuit operable to receive an input from a charge pump and a drive circuit connected to an output of the input circuit. The drive circuit is operable to provide an output matching the input to the input circuit when a voltage source powering the input circuit and the drive circuit is stable, and to introduce a contrary voltage change on the buffered output when the voltage source is noisy, with the contrary voltage change being contrary to a voltage change on the voltage source due to noise.

摘要： A time division multiplex data recovery system using a closed-loop phase lock loop (PLL) and delay locked loop (DLL) is disclosed. In other words, one closed loop comprises both a phase locked loop (PLL) and a delay locked loop (DLL) in a novel time division multiplex data recovery system. This new architecture comprises a 4 stage Voltage Controlled Oscillator (VCO) used to generate 8 clock signals, 45 degrees phase shifted from one another, for 8 receivers to do the oversampling. An interpolator tracks the received data signal and feeds it back to the Phase/Frequency Detector (PFD). The PFD has a second input of the reference clock which the PFD uses along with the interpolator input to correct the frequency of the PLL. The PLL operates at a high bandwidth. The DLL's bandwidth is several orders lower than the PLL. The DLL activates only a multiplexer and an interpolator continuously, thereby drawing a minimum amount of power.

摘要： There are numerous types of dividers that have been employed at various frequency ranges. For many very high frequency ranges (i.e., above 30 GHz), dividers in CMOS have been developed. However, many of these designs use multiple stages. Here, however, a single stage divider has been provided that is adapted to operate at very high frequencies (i.e., 120 GHz). To accomplish this, it uses parasitic capacitances in conjunction with inductor(s) to form an LC tanks so as to take advantages of parasitics that normal degrade performance.
