Abstract:
The present invention provides a hybrid analogue-to-digital converter (ADC) that comprises a successive approximation analogue-to-digital converter (SAR-ADC); and a time based integrating and cyclic analogue-to-digital converter (CYC-ADC) integrated with the SAR-ADC. An input analogue signal is processed through the SAR-ADC to output a first output constituting most significant bits (MSBs) of an digital output signal and a residue signal, the residue signal is further processed through the CYC-ADC to output a second output constituting the least significant bits (LSBs). A method of carrying out the analogue to digital conversion is also provided.
Abstract:
Disclosed is a force-balanced piezoresistive 3-axis accelerometer. An exemplary accelerometer (100) comprises a proof mass (104) which is coupled to a plurality of meanders (103), which further couple to a plurality of anchor pads (102) that extends out from each meander (103). The proof mass (104), meanders (103) and anchor pads (102) are integrally fabricated multilayer construct which comprises a base silicon layer (201), insulator 1 (202), insulator 2 (204), metal 1 (203) and metal 2 (205) arranged in an intermittent fashion and fabricated through CMOS compatible fabrication process. Piezoresistive sensing means is used in detecting acceleration in three degree of freedoms or directions in which piezoresistors (206) embedded within the multilayer construct are used to sense the movement of proof mass (104) and meanders (103) upon external force which exerted on the proof mass (104). Electrical signals upon the sensing are then generated and processed by electrical circuitry to provide DC biasing on respective anchor pads (102) to produce x-, y- and z-direction acceleration data in terms of magnitude and direction. The accelerometer is also designed with self- test capability in which the meanders (103) perform self-test by bending at least one meander while keeping other meanders stationary and measuring z-displacement. The resulting accelerometer has the potential for low power consumption due to DC biasing, low cost and high-accuracy operation over wide temperature range due to additional Wheatstone bridge circuit embedded within the multilayer construct.

Abstract:
The present invention provides an piezoelectric based energy harvester apparatus [20] consisting of a specially designed mechanical structure, hollow cylindrical structure [30] with a piezoelectric cantilever bridge [34] within its chamber, that upon exposure to the collected rain water incoming from the roof structure [24] into the post [26], will move or vibrate due to buoyant force of the strategically trapped rain water. With the structure built-in mechanical cantilevers bridge [34] that has piezoelectric properties, the vibration of the cylindrical structure [30] is followed by the generation of micro energy. Therefore, besides serving its traditional purpose for protection, post/pillar can also be used to produce energy which can power up low power electronic devices such as for precision agriculture application. This apparatus can also act as an alternative energy harvester during raining season where no sunlight is available.
