Steven Terryn, Dieter Joos: Bandwidth calibration of active filter. STMicroelectronics Belgium, Lisa K Jorgenson, James H Morris, Wolf Greenfield & Sacks P C, April 6, 2010: US07692484 (3 worldwide citation)

An active RC filter has an op-amp and a biasing circuit arranged to bias the op-amp to set a gain bandwidth product of the op-amp according to a desired pole frequency of the filter. The biasing circuit is operable according to an output of an RC calibration circuit. The op-amp can be an OTA transco ...

Dieter Joos, Marc Borremans: Differential low noise amplifier with low power consumption. STMicroelectronics, Lisa K Jorgenson, James H Morris, Wolf Greenfield & Sacks P C, February 13, 2007: US07176759 (3 worldwide citation)

A low noise differential amplifier has a pair of single ended common-gate or common-base circuits and cross coupling of an input of one of the pair to the gate or base of the other one of the pair. This cross-coupling puts the differential input voltage over the Gate-Source of the common-gate transi ...
