Abstract: This disclosure relates to a method and system for efficiently and analytically generating spectra associated with transitions between thermal states in a multi-mode bosonic system using a classical algorithm to compute Fourier components of the transition spectra of the multi-mode bosonic system based on a representation space sampling method inspired by quantum Gaussian boson sampling followed by an inverse Fourier transform. The disclosed method and system particularly apply to efficient estimation of molecular vibronic spectra. For example, an exact solution of the Fourier components of molecular vibronic spectra at zero temperature may be analytically computed in a representation space by using, for example, a positive P-representation of the multi-mode bosonic vibronic quantum states of the molecule.

Abstract: Techniques are provided to tune a gate-drive control signal for a switching device. In an aspect, a device is provided that includes a dead-time generator circuit, a first dead-time tuner circuit and a second dead-time tuner circuit. The dead-time generator circuit generates a control signal for a first switching device that is coupled to a second switching device via a switching node.

Abstract: A charge/discharge protection circuit protects a battery from inadvertent shorting on a charger node that can connect to a charger or to a power supply of a portable electronic device. A single n-channel power transistor has a gate that controls a channel between the battery and the charger node. The gate is connected to the charger node by a gate-coupling transistor to turn off the power transistor, providing battery isolation. The gate is driven by a voltage-boosted clock through a switch activated by an enable signal. The enable signal also activates a grounding transistor to ground a gate of the gate-coupling transistor. A comparator compares voltages of the charger and battery nodes, and the compare output is latched to generate the enable signal. An inverse enable signal activates a second switch that drives the voltage-boosted clock to the gate of the gate-coupling transistor to turn off the power transistor.

Abstract: Systems and methods which provide an oscillator circuit outputting non-overlapping trigger signals throughout a range of operating voltages using a reset-set (RS) flip-flop type circuit configuration are shown. Embodiments utilize output driver buffers internal to the RS flip-flop circuit configuration to provide oscillator feedback delay. Feedback control circuitry may be implemented to ensure that the delay associated with any one driver buffer does not solely provide the feedback delay. Embodiments further implement input delay circuitry adapted to maintain a relatively constant reset and set input feedback delay ratio throughout a large range of operating conditions.

Abstract: An oscillator operates at a very low voltage yet has a duty cycle that is set by a ratio of capacitors that are charged and discharged. Sub-threshold p-channel transistors conduct sub-threshold currents below the normal threshold voltage, and drive set and reset inputs of a set-reset S-R latch. The S-R latch drives the oscillator outputs. The oscillator outputs feed back to charging p-channel transistors that charge one plate of the capacitors. During half of the cycle, the charging p-channel transistor is off, allowing one plate of the capacitors to discharge through an n-channel discharge transistor. After a period of discharge determined by the capacitance of the capacitor, the gate of a sub-threshold p-channel transistor falls enough for sub-threshold current to flow, triggering the set or reset input of the S-R latch. Since sub-threshold currents are needed to toggle the S-R latch, the oscillator begins to oscillate below the threshold voltage.
