Abstract: The present disclosure provides a feedback control system and method for a bidirectional VCM. The system employs an analog core that is common to both the PWM and linear modes of operation. The analog core includes a feedback mechanism that determines the error in the current flowing through the motor. The feedback mechanism produces an error voltage that corresponds to the current error, and applies the voltage to a control driver. The control driver then controls the motor, based on the error voltage, in either a PWM or linear mode. By sharing a common core, the switching time between modes is improved. Furthermore, the output current error between modes is reduced.

Abstract: It is often desirable to distinguish between an open circuit condition and a no signal condition. In both cases an input signal may be absent, but only one of these events represents a failure of the equipment. The present disclosure provides a way to use a difference amplifier to check for open circuit events, without requiring additional circuitry at the input of the amplifier.

Abstract: A power factor correction device for providing tolerance to a fault condition in an input supply can include a first boost circuit, a second boost circuit, and a controller circuit. The controller circuit can interleave operation of the first boost circuit and operation of the second boost circuit such as to generate an output voltage when the input supply is received at the power factor correction device. The controller circuit can route, in response to the fault condition, a stored supply of the second boost circuit to an input of the first boost circuit. The controller circuit can control the first boost circuit to maintain the output voltage.

Abstract: A system having two or more sensing nodes coupled to a control node using a serial communication channel having separate transmit and receive circuits, where each sensing node includes an ADC circuit and a microcontroller, operation of the ADC circuit in each sensing node is concurrently synchronized by the control node using the transmit circuit (e.g., with respect to the control node) of the serial communication channel. The control node can synchronize operation of two or more ADC circuits in separate sensing nodes without using shared clocks or other control signals.

Abstract: The disclosed technology generally relates to forming metallization structures for integrated circuit devices by plating, and more particularly to plating metallization structures that are thicker than masking layers used to define the metallization structures. In one aspect, a method of metallizing an integrated circuit device includes plating a first metal on a substrate in a first opening formed through a first masking layer, where the first opening defines a first region of the substrate, and plating a second metal on the substrate in a second opening formed through a second masking layer, where the second opening defines a second region of the substrate. The second opening is wider than the first opening and the second region encompasses the first region of the substrate.

Abstract: A gas sensor package is disclosed. The gas sensor package can include a housing defining a first chamber and a second chamber. An electrolyte can be provided in the first chamber. A gas inlet can provide fluid communication between the second chamber and the outside environs. The gas inlet can be configured to permit gas to enter the second chamber from the outside environs. An integrated device die can be mounted to the housing. The integrated device die can comprise a sensing element configured to detect the gas. The integrated device die can have a first side exposed to the first chamber and a second side exposed to the second chamber, with the first side opposite the second side.

Abstract: Apparatus and methods provide predistortion for a phased array. Radio frequency (RF) sample signals from phased array elements are provided along return paths and are combined by a hardware RF combiner. Phase shifters are adjusted such that the RF sample signals are phase-aligned when combined. Adaptive adjustment of predistortion for the amplifiers of the phased array can be based on a signal derived from the combined RF sample signals.

Abstract: Aspects of this disclosure relate to transmitting and/or receiving a frequency-shift keying signal including a packet that includes a preamble and a payload. The preamble has a first modulation index that has a smaller magnitude than a second modulation index of the payload. This can enhance frequency correction in a receive device that receives the packet.

Abstract: Differential sampling circuits may be adversely affected by changes in common mode voltage. Changes in the common mode voltage may alter the on resistance of transistor switches which it turn may mean that small signal changes are not correctly observed against a bigger common mode signal. The present disclosure relates to a way of improving the ability to resolve small differential signal changes by varying the supply or drive voltage to a component to compensate for common mode voltage changes.
