Patent number: 9479125Abstract: A system and method for adjusting a common mode output voltage in an instrumentation amplifier is provided. In one aspect, the common mode output voltage is increased or decreased with respect to the common mode input voltage to enable high amplification of the signal input to the instrumentation amplifier. Moreover, the common mode output voltage can be driven to (or approximately to) a target voltage value such as, but not limited to, half the supply, even if the common mode input voltage is close to supply or ground rail voltage. Thus, a high amplification of the differential input voltage can be obtained and utilized for various applications requiring rail to rail input.Type: GrantFiled: July 16, 2014Date of Patent: October 25, 2016Assignee: SEMTECH CORPORATIONInventors: Olivier Nys, Francois Krummenacher

Patent number: 9214938Abstract: Electronic interface and method for reading a capacitive sensor that includes one input capacitor (30) or several input capacitors, in which the capacitive sensor is excited with a two-level voltage (Vlow, Vhigh) and read by a charge-sense amplifier whose output is sampled in four successive instants. An evaluation unit (333) is arranged to compute two difference values (V12, V34) between two pairs of samples corresponding to different voltage levels and to combine said difference values into an output value (V_out_raw) proportional to the charge transferred to the input of the charge-sense amplifier and an error value (error_bit) sensitive to a time derivative of a noise current din/dt.Type: GrantFiled: November 27, 2012Date of Patent: December 15, 2015Assignee: Advanced Silicon SAInventors: Hussein Ballan, Francois Krummenacher

Publication number: 20070046369Abstract: A method and apparatus for an ultra-high sensitivity, low cost, passive (no battery) low-power energy harvesting data transmitting circuit energy, such as a RFID (Radio Frequency IDentification) tag integrated circuit “chip.” By using combinations of special purpose design enhancements, the low-power energy harvesting passive data transmitting circuit, such as the RFID tag chip, operates in the sub-microwatt power range. The chip power should be derived from a low-microwatt per square centimeter RF field radiated to the RFID tag antenna from the tag reader (interrogator) or derived from a suitable low signal source, such as a sonic transducer (e.g., a piezoelectric transducer or a low level DC source, such as a bimetallic or chemical source).Type: ApplicationFiled: July 22, 2006Publication date: March 1, 2007Inventors: Robert Schober, Ion Opris, Francois Krummenacher
