Abstract: A differential ring voltage‐controlled oscillator (DRVCO) is proposed in this paper as one of the critical blocks in communication systems. It consists of four stages of delay cells connected in a chain, creating a ring structure with auxiliary path interconnections. The oscillation frequency of the DRVCO can be controlled by adjusting the tuning voltage that controls the charging current. To achieve the desired performance for wireless applications, the Wu active inductor, which is a low‐noise and high‐qualit… Show more
