摘要： A DC-DC converter has high-side power and low-side power transistors connected in series between supply terminals, an inductor connected between the power transistors and an output terminal. A comparator compares the output voltage with a reference voltage. A detector detects when inductor current approaches zero. A timer is configured to determine a minimum ON time of the high-side power transistor optimized for a particular value inductor. A current detector detects current flow in the back-gate diode of the low-side power transistor. timer is configured to determine an overriding ON time in response to the back-gate current detector. Logic provides control signals to gate power transistors in response to the comparator and the longer one of the minimum ON time and the overriding ON time. The minimum ON time for the high-side power transistor is adjusted in response to the actual inductance of the inductor.

摘要： An integrated circuit device (10) with a bonding surface (12) directly over its active circuitry, and a method of making such integrated circuits (FIGS. 2A-2E). To make the bonding surface (12), a wafer (20) is provided with vias (24) to its metallization layer (21) and then coated with a seed metal layer (25). A plating pattern (26) is formed on the wafer (20), exposing portions of the seed metal layer (25) and blocking the rest of the seed metal layer (25). These exposed portions are plated with successive metal layers (27, 28, 29), thereby forming a bonding surface (12) having a number of layered stacks (200) that fill the vias (24). The plating pattern and the nonplated portions of the seed metal layer (25) are then removed.

摘要： A low power DC-DC converter includes a converter stage coupled to an input node, and having a low side switch and a rectifier switch. A peak current detector senses a current at the low side switch and a zero current detector senses a current at the rectifier switch. It is configured to set the low side switch to a non-conductive state and the rectifier switch to a conductive state if the peak current detector detects a predetermined peak current. It is configured to set the rectifier switch to a non-conductive state if the zero current detector detects zero current at the rectifier switch. A time interval between subsequent current peaks is triggered by a charge comparator receiving an average current fed to the low side and rectifier switches from the input node and a reference current coupled to the charge comparator by a reference current source.

摘要： A serial interface circuit for a single logic input pin of an electronic system, comprising a decoder for converting a pulse width modulated input signal applied to the pin to a sequence of logic low and logic high values. The decoder comprises an up/down counter with a count input connected to a clock source, an edge detection circuit detecting rising and falling edges of the input signal. The edge detection circuit is connected to the up/down counter to start up counting from a reset value upon detection of an edge in a first direction and to start down counting from a current count upon detection of an edge in a second direction. The decoder further comprises a bit value deciding circuit that delivers a first logic value when the count of the up/down counter is above the reset value on detection of an edge in the second direction and delivers a second logic value when the count of the up/down counter is at or below the reset value on detection of an edge in the second direction.

An energy harvesting system which uses an AC generator for generating electrical energy out of mechanical energy, a rectifier circuit which is connected with the input to the output of the AC generator and a low power wireless system as application unit. A method of rectifying an AC output voltage of an AC generator for use in an energy harvesting application.
