Voltage-controlled Oscillator (VCO) is a prominent part that has been used to generate a stable frequency for the high-frequency transceiver system. This survey encompasses a comparative analysis of two commonly used VCO architectures: the Ring VCO and LC-VCO. The Ring VCO has been constructed with the collection of ring delay cells.

2025年3月4日 · 环形振荡器一直是一种流行的测试工具，用于测量反相器或其他数字门的门延迟时间。 随着差分环压控振荡器（VCO）的发展，PLL的电源抑制性能得到了显著的改善，PLL的应用范围也扩展到了时钟产生和时钟恢复系统中。 当设计差分延迟单元时， 通过交换末级和第一级反相器之间连接的极性，环形振荡器可以与偶数个差分反相器一起工作，如图（b）所示。 如果级数是4的倍数，差分环VCO可以产生0 kHz和90 kHz的正交相位，这对于时钟和时钟数据恢 …

Abstract – This paper gives a performance, power and area comparison of LC vs. Ring VCOs for application to PLL designs in a standard 90 nm digital CMOS process. We develop an analytical framework for de-termining the best match for a high-speed clock synthe-sizer design based on the constraints of the application.

A differential ring Voltage Controlled Oscillator (VCO) with a controllable KVCO is introduced. The capability to control KVCO enables post-fabrication calibration of VCO gain, in order to reduce its vulnerability to Process, Voltage, and Temperature (PVT) variations.

2021年12月14日 · On the contrary, a ring VCO offers wide tuning range, high frequency operations, and low power consumption with an easy integration which provides small chip-area. The ring VCO provides low resolution and slightly higher phase noise performance [7, 8], but they are preferred to save chip-area.
