Calibration of radix errors using Least-Significant-Bit (LSB) averaging in a Successive-Approximation Register Analog-Digital Converter (SAR-ADC) during a fully self-calibrating routine
A self-calibrating Analog-to-Digital Converter (ADC) performs radix error calibration using a Successive-Approximation Register (SAR) to drive test voltages onto lower-significant capacitors. The final SAR code is corrected by performing LSB averaging on LSB averaging capacitors and then accumulated, and the measurement repeated many times to obtain a digital average measurement. An ideal radix or ratio of the measured capacitor's capacitance to a unit capacitance of an LSB capacitor is subtracted from the digital average measurement to obtain a measured error that is stored in a Look-Up Table (LUT) with the ideal radix. Radix error calibration is repeated for other capacitors to populate the LUT. During normal ADC conversion, the SAR code obtained from converting the analog input is applied to addresses the LUT, and all ideal radixes and measured errors for 1 bits in the SAR code are added together to generate an error-corrected digital value. |

Medium wave infrared (MWIR) and long wavelength infrared (LWIR) operating microbolometer with raised strut design
A semiconducting microbolometer sensor for detecting electromagnetic waves in the medium wavelength infrared (MWIR) and long-wavelength infrared (LWIR) is provided. A preferred embodiment provides a substrate layer, a bottom and top support structure with a strut-based mesh design, a meandered electrode layer that follows the top support structure design, a bolometer sensing material with a high TCR, and a disk-shaped absorber on top of the sensing material to maximize the heat flux absorption on the sensor. The bottom support of the sensor suspends the top support mesh, creating an air cavity. This air cavity along with the strut based mesh design and optimized thickness, dimension and shape of the layers contributed towards minimizing the thermal conductance of microbolometer and hence improved the figures of merits—responsivity, detectivity, noise equivalent power and noise equivalent temperature difference of microbolometer. |
