High-voltage, CMOS-enabled, and silicon wire array decorated photovoltaic module for driving smart dimming glasses

Yung‐Jr Hung, Ying‐Chi Chen, Yi‐Chen Wu, Chung-Ming Yang

We demonstrate a miniaturized silicon photovoltaic (PV) module in standard bulk CMOS for driving smart dimming glasses. The PV is front-illuminated to leverage the high-lifetime silicon denuded zone and is decorated with silicon wire array to reduce the optical reflectivity at silicon/intermediate …

A 3 mW 6-bit 4 GS/s Subranging ADC With Subrange-Dependent Embedded References

Chung-Ming Yang, Tai-Haur Kuo

A subranging analog-to-digital converter (ADC) with reference-embedded comparators (RECs) is proposed. By adjusting the bias current and/or body voltage of the REC's input differential pair, the REC offset can be adjusted to a specific voltage equal to a reference voltage referred to …

An 8-bit 1.5GS/s Subranging ADC with Level-Shift Operation and Calibration Techniques

Chung-Ming Yang, Tai-Haur Kuo

This work presents a high-speed low-power subranging analog-to-digital converter (ADC). The prototype achieves a subranging operation with a level-shift operation technique, which has a higher speed compared with the conventional subranging architecture. A background calibration is proposed to overcome the non-idealities from …

A 3mW 6b 4GS/s Subranging ADC with Adaptive Offset-Adjustable Comparators

Chung-Ming Yang, Tai-Haur Kuo

This work implements a 3mW 6b 4GS/s subranging ADC in 28nm CMOS. With the proposed adaptive offset-adjustable comparators (OACs), the subranging architecture is free of both conventional reference-voltage switching to increase speed and the resistor ladder to save power. A proposed calibration …

A compact low-power flash ADC using auto-zeroing with capacitor averaging

Ching-Chung Lee, Chung-Ming Yang, Tai-Haur Kuo

This paper proposes efficient methods to reduce the cost and power consumption of flash analog-to-digital converters (ADCs). An auto-zeroing technique is incorporated with a low-complexity low-power capacitor averaging network for efficient offset cancellation and signal interpolation. Therefore, the cost and power consumption …
