A 1×32 TDC Array With 0.056% Pixel-to-Pixel Variation Using a Global Timer Architecture for LiDAR Applications

A 1×32 TDC Array With 0.056% Pixel-to-Pixel Variation Using a Global Timer Architecture for LiDAR Applications 150 150
Author(s): Hsi-Hao Huang, Zong-Rui Cao, Ying-Ying Cheng, Jia-Yu Lin, Chen-Yi Lee

Abstract:

This letter presents a low pixel-to-pixel variation (PPV) time-to-digital converter (TDC) array designed for light detection and ranging (LiDAR) applications. The TDC array is implemented in a 0.18 μm HV CMOS process, integrated with a single-photon avalanche diode (SPAD) array. SPAD-based LiDAR systems require high-precision timing resolution across the entire sensing …

A 200 GHz Wideband and Low-Power Direct-Downconversion Receiver Element in 16 nm FinFET Technology

A 200 GHz Wideband and Low-Power Direct-Downconversion Receiver Element in 16 nm FinFET Technology 150 150
Author(s): Ethan Chou, Hesham Beshary, Nima Baniasadi, Ali M. Niknejad

Abstract:

This letter presents a wideband and low-power direct-downconversion 200 GHz receiver element for digital-beamforming applications implemented in 16 nm FinFET technology. Wideband and low integrated receiver noise figure of 9.8 dB across a 21 GHz baseband bandwidth is realized with a differential low-noise amplifier leveraging an active input balun stage, while wideband gain of 29 …

A 0-to- 10μF Off-Chip Output Capacitor-Scalable Boost Converter Achieving 96.68% Peak Efficiency

A 0-to- 10μF Off-Chip Output Capacitor-Scalable Boost Converter Achieving 96.68% Peak Efficiency 150 150
Author(s): Hyeon-Ji Choi, Joo-Mi Cho, Hyo-Jin Park, Seok-Jun Lee, Sung-Wan Hong

Abstract:

This letter presents an off-chip output capacitor (CO)-scalable (OCS) boost converter. The proposed OCS boost converter is possible to operate both with and without the off-chip CO. In addition, it operates in a whole conversion ratio (CR) range over 1 while maintaining a small current ripple of an inductor, resulting …
