A 0.4-V 32-kHz Pulse-Injection Temperature-Compensated Crystal Oscillator With Sub-Cycle CL Modulation and DLL-Reused Temperature Sensor

A 0.4-V 32-kHz Pulse-Injection Temperature-Compensated Crystal Oscillator With Sub-Cycle CL Modulation and DLL-Reused Temperature Sensor 150 150
Author(s): Haihua Li, Pui-In Mak, Rui P. Martins, Ka-Meng Lei

Abstract:

This article presents a 0.4-V 32 kHz pulse-injection (PI) temperature-compensated crystal oscillator (TCXO) that incorporates subcycle capacitive load ( $C_{\text {L}}$ ) modulation for frequency compensation. The proposed TCXO compensates for the crystal’s frequency deviation ( $\Delta f$ ) by dynamically adjusting the enabling duration of the additional $C_{\text {L}}$ within each …

A Low-Jitter Fractional-N Digital PLL Using a Quantization-Error-Compensating BBPD and an Orthogonal-Polynomial-Based LMS Calibration

A Low-Jitter Fractional-N Digital PLL Using a Quantization-Error-Compensating BBPD and an Orthogonal-Polynomial-Based LMS Calibration 150 150
Author(s): Munjae Chae, Seheon Jang, Seungjae Lee, Jaehyouk Choi

Abstract:

This work presents a 10.0–11.5-GHz fractional- $N$ digital phase-locked loop (DPLL) using the quantization-error-compensating bang–bang phase detector (QEC-BBPD) that can minimize both the static delay ( $T_{\mathrm {S}}$ ) and the dynamic delay ( $T_{\mathrm {D}}$ ) required for removing the delta-sigma modulator’s ( $\Delta \Sigma $ M) quantization-error (Q-error). Since the …

Abstract:

In the field of power converters for data centers, the two-stage architecture has received widespread attentions due to its various advantages. Especially, the switched-capacitor voltage regulator (SCVR) becomes popular as the second-stage converter owing to its high efficiency and power density. However, the SCVR suffers from poor voltage regulation and …
