A sense input voltage is obtained on an output terminal of a sensing circuit that is not directly connected to the switching node, as a second input signal to the CB. A voltage is generated on a first output terminal of the CB and is selected such that the CB can use its first and second input signals to infer the current through the inductor. A pulse width modulation (PWM) signal is generated on a second output terminal of the CB, based on the inferred current through the inductor; the second output signal from the CB is provided to a PWM input terminal of the power switch and driver block.

  • Patent number: 10816569
    Abstract: Z-axis microelectromechanical systems (MEMS) accelerometers are described. The z-axis MEMS accelerometers are of a teeter-totter type, having a pivoting beam suspended above a substrate. A non-uniform gap distance between the pivoting beam and the substrate is provided to increase the sensitivity of the accelerometer to z-axis acceleration. In some embodiments, the non-uniform gap distance is created by one or more substrate layers, such as one or more layers of polysilicon on the substrate above which the pivoting beam is suspended. In some embodiments, the non-uniform gap distance is created by the use of one or more bumps on the beam. In some embodiments, both substrate layers and bumps are used to provide a non-uniform gap distance for different electrodes of the accelerometer. The non-uniform gap distance may include a gap of reduced height, resulting in increased sensitivity of the accelerometer to z-axis accelerations.
