Abstract: A low voltage to high voltage (LV2HV) conversion circuit has an input configured to receive an input signal (at a relatively low voltage) and an output configured to generate an output signal (at a relatively high voltage). The LV2HV conversion circuit includes a voltage to current conversion circuit referenced to the relatively low voltage and configured to convert a voltage of the input signal to a first current, wherein a magnitude of the first current is dependent on said voltage of the input signal and a gain setting value. A current mirroring circuit mirrors the first current and outputs a second current. A current to voltage conversion circuit converts the second current to a voltage of the output signal. The current mirroring circuit and current to voltage conversion circuit are referenced to the relatively high voltage.

Abstract: An integrated electronic detector operates to detecting a variation in potential on an input terminal. The detector includes a MOS transistor having a drain forming an output. Variation in drain current is representative of the variation in potential. A bipolar transistor has a base forming the input terminal and a collector electrically connected to the gate of the MOS transistor. The detector has a first configuration in which the bipolar transistor is conducting and the MOS transistor is turned off. The detector has a second configuration in which the bipolar transistor is turned off and the MOS transistor is in a sub-threshold operation. Transition of the detector from the first configuration to the second configuration occurs in response to the variation in potential.
Abstract: A Schmitt trigger circuit having an input coupled to a current summing junction. A trickle current source generates a trickle current applied to the current summing junction. A bandgap current source generates a bandgap current applied to the current summing junction (wherein the bandgap current is fixed when a supply voltage exceeds a threshold). A variable current source generates a variable current applied to the current summing junction (wherein the variable current varies dependent on the supply voltage). At the current summing junction, the variable current is offset against the trickle and bandgap currents with respect to generating a voltage that is sensed at the Schmitt trigger circuit input.

Abstract: An electronic device includes a single-photon avalanche diode (SPAD) array and readout circuitry coupled thereto. The readout circuitry generates a depth map having a first resolution, and a signal count map having a second resolution greater than the first resolution. The depth map corresponds to distance observations to an object. The signal count map corresponds to intensity observation sets of the object, with each intensity observation set including intensity observations corresponding to a respective distance observation in the depth map. An upscaling processor is coupled to the readout circuitry to calculate upscaling factors for each intensity observation set so that each distance observation has respective upscaling factors associated therewith. The depth map is then upscaled from the first resolution to the second resolution based on the respective upscaling factors.
Abstract: A method for forming fins includes growing a SiGe layer and a silicon layer over a surface of a bulk Si substrate, patterning fin structures from the silicon layer and the SiGe layer and filling between the fin structures with a dielectric fill. Trenches are formed to expose end portions of the fin structures. A first region of the fin structures is blocked off. The SiGe layer of the fin structures of a second region is removed by selectively etching the fin structures from the end portions to form voids, which are filled with dielectric material. The silicon layer of the fin structures is exposed. The SiGe layer in the first region is thermally oxidized to drive Ge into the silicon layer to form SiGe fins on an oxide layer in the first region and silicon fins on the dielectric material in the second region.

Abstract: A switching regulator includes circuitry for reducing conductive emissions caused when the regulators switch from one transistor switch to the other. The switching regulator includes at least one switch with a diode connected from the source to the drain of at least one of the transistor switches. When the regulator switches from one transistor switch to the other, the circuitry initiates turning on the switch with a relatively small, current-limited signal, waits for the diode across the recently turned off switch to complete reverse recovery, and then quickly turns the new switch fully on.
