摘要

本文提出了一种使用门控环形振荡器及时间斜移整形技术的2-0级联结构的Δ型TDC.该TDC使用了一个环形DTC和基于时间寄存器的时域加法器

DTC通过与GRO-TDC共享量化器从而无需校准并且降低了功耗.通过将GRO量化器的输出分割为MSB和LSB部分

环形DTC的精度要求被进一步降低.利用该时间斜移整形技术

GRO的时间斜移误差被一阶整形

同时死区效应被解决.与此同时

实现了量化噪声的二阶整形.该项技术易于在宽带和低功耗方面得到应用.

Abstract

A 2-0 cascade gated-ring-oscillator (GRO) based Δ time-to-digital converter (TDC) using time-skew shaping technique is presented in this paper. The proposed TDC includes a ring digital-to-time converter (Ring-DTC) and a time-register (TR) based time-domain adder. By sharing the intrinsic gated-ring quantizer of GRO-TDC

the Ring-DTC has performed no additional matching requirement

calibration free and low power consumption. By dividing the outputs of the GRO quantizer into an MSB segment and an LSB segment

the resolution requirement of Ring-DTC is further released. With the proposed time skew shaping technique

the time-skew of GRO is 1 order shaped

and the dead-zone effect is solved. At the same time

2 order quantization noise shaping is achieved. This technique is simple to implement and well suited for low-power and wide-band applications.
