摘要： A current sense device for a power transistor is described. The power transistor is formed in a cellular structure including a cellular array of transistor cells. The current sense device includes multiple transistor cells in the cellular array of transistor cells of the power transistor being used as sense transistor cells. The sense transistor cells are evenly distributed throughout the cellular array where the source terminal of each sense transistor cell is electrically connected to a first node through a metal line in the first metal layer and through a metal line in the second metal layer where the metal lines are electrically isolated from the metal lines connecting the transistor cells of the power transistor. The sense transistor cells measure a small portion of the current flowing through the power transistor based on the size ratio of the current sense device and the power transistor.

摘要： A PWM regulator is operated either a buck mode or a boost mode depending on whether the input voltage is above or below the desired regulated output voltage. The technique uses two sawtooth ramps 180 degrees out of phase. Where the two ramps cross each other is a buck/boost transition level. An error voltage, corresponding to a required duty cycle to achieve a regulated voltage, is compared to the two ramps. The transition from one mode to the other occurs when the error voltage passes the buck/boost transition level of the two ramps. A logic circuit supplies PWM pulses to either buck switching transistors or the boost switching transistors in a power stage of the regulator, depending on the whether the error voltage is above or below the buck/boost transition level, to achieve the regulated voltage.

摘要： A circuit (10, 100) is used to perform voltage regulation. In one embodiment, a voltage regulator (11) is used in conjunction with an output transistor (24) to form a circuit (10) which operates to regulate the voltage drop from a first node (30) to a second node (28). This second node (28) may be used to provide power to circuitry (27). The areas of several transistors (20–25) in circuit (10) may be adjusted so that negative and positive temperature coefficients may be balanced such that the circuit (10) behaves as desired over a range of voltages and temperatures. Note that in one embodiment, circuit (10) is a 2-terminal device.
