Patent number: 7945834Abstract: A testing circuit has scan chain segments (62,64,60) defined between parallel inputs (wpi[0] . . . wpi[N?1]) and respective parallel outputs (wpo[0] . . . wpo[N?1]). The scan chain segments comprise a bank (62) of cells of a shift register circuit, a core scan chain portion (62), a first bypass path around the core scan chain portion (62) and a second bypass path around the bank (60) of cells of the shift register circuit. This architecture enables loading of data in parallel into the core scan chain, or into the shift register (WBR). In addition, each scan chain segment also has a series latching element (80), and this provides additional testing capability. In particular, the shifting of data between the latching elements (80) can be used to test the bypass paths while the internal or external mode testing is being carried out. This testing can thus be part of a single ATPG procedure.Type: GrantFiled: October 18, 2006Date of Patent: May 17, 2011Assignee: NXP B.V.Inventors: Tom Waayers, Richard Morren

Patent number: 7944306Abstract: The present invention relates to a bias control circuit and method for supplying a bias signal to at least one stage of an amplifier circuit, wherein a dual bias control is provided by generating a bias current and additionally using this bias current to derive a control signal for limiting a supply voltage of the at least one amplifier stage in response to the control signal. Thereby, a compression of the output signal of the amplifier stage, which results from the voltage limitation, can be realized in addition to the base current steering. This leads to a decrease in small signal gain and thus reduced output noise.Type: GrantFiled: October 5, 2005Date of Patent: May 17, 2011Assignee: NXP B.V.Inventors: Dmitri Pavlovitch Prikhodko, Remco Ooijman, Pieter Lok, Jeroen Sluijter
