Abstract: A digital delay line includes a plurality of delay cells therein. The delay line is configured to delay a periodic signal received at a first input thereof by passing the periodic signal through a selected number of the plurality of delay cells, in response to a discontinuous thermometer code that encodes the selected number. A code converter is provided, which includes a group bit decoder, a shared bit decoder and a code output cell array, which are collectively configured to generate the discontinuous thermometer code in response to a binary control code.

Abstract translation: 数字延迟线在其中包括多个延迟单元。 延迟线被配置为响应于编码所选择的数量的不连续的温度计代码，通过使周期信号通过选定数量的多个延迟单元来延迟在其第一输入处接收到的周期信号。 提供了一种代码转换器，其包括组位解码器，共享位解码器和代码输出单元阵列，它们被共同配置为响应二进制控制代码产生不连续的温度计代码。

Abstract: Provided are a delay locked loop (DLL) that may can be included in a data processing device and may include a duty correction circuit, and a duty correction method of such a DLL. The duty correction method includes aligning a second transition of an output clock at a first transition of a clock for duty correction, sampling the clock for duty correction at the first transition of the output clock to detect an error of a duty cycle, and performing duty correction using a skewed gate chain according to the detected error of a duty cycle.
