Patent number: 11393183Abstract: A substrate and a covering structure coupled to the substrate form a chamber. The chamber houses an emitter configured to emit a radiation, a resonant reflector, a detector, and a fixed reflector. First and second windows extend through the covering structure. The emitter, the first reflector and the second reflector are reciprocally arranged such that radiation emitted from the emitter is reflected by the fixed reflector towards the MEMS reflector for further reflection towards the first window to form an output signal. The detector and the second window are reciprocally arranged such that an incoming radiation passing through the second window is received by the detector. The electronic module can be used for a 3D sensing application.Type: GrantFiled: March 23, 2020Date of Patent: July 19, 2022Assignee: STMicroelectronics S.r.l.Inventors: Roberto Carminati, Fabio Bottinelli

Patent number: 8248108Abstract: A comparator formed by first and second stages. The second stage is formed by a pair of output transistors connected between a power-supply line and respective output nodes; a pair of bias transistors, connected between a respective output node and a current source; a pair of memory elements, connected between the control terminals of the output transistors and opposite output nodes; and switches coupled between the control terminals of the respective output transistors and the respective output nodes. In an initial autozeroing step, the first stage stores its offset so as to generate an offset-free current signal. In a subsequent tracking step, the second stage receives the current signal and the memory elements store control voltages of the respective output transistors. In a subsequent evaluating step, the first stage is disconnected from the second stage and the memory elements receive the current signal and switch the first and the second output node depending on the current signal.Type: GrantFiled: March 18, 2010Date of Patent: August 21, 2012Assignee: STMicroelectronics S.r.l.Inventors: Manuel Santoro, Fabio Bottinelli
