Ripple-based adaptive constant on-time (RBACOT) control with virtual ripple are conceptually simple, fast dynamic transient responses at lower duty cycle application, and lower component count. This control schema solves instability issue of sub-harmonic oscillation when ceramic capacitors are used. These characteristics make the regulators well-suited,(More)
This paper examines why an existential polarity wh-subject or a you-NP subject is not allowed in Chinese A-not-A questions. Two kinds of syntactic approaches proposed in the literature that deal with unacceptable existential polarity wh-subjects in A-not-A questions are reviewed.
