Abstract: PURPOSE: To provide the voltage-controlled oscillator circuit which can output clock signals of precise oscillation frequencies stably in a low-frequency range to a high-frequency range, even if the oscillation frequency of a voltage- controlled oscillation part becomes high. CONSTITUTION: This voltage-controlled oscillation circuit is composed of a level conversion circuit, an amplitude control circuit, a voltage-controlled oscillation part formed by connecting differential type delay cells in a ring shape, and an output level converting circuit. The level converting circuit has limiters 11 and 14, which limit maximum values Imax and Imin of a control current and only an area where the voltage-controlled oscillation part is in normal oscillating operation is used through those limiters to improve the duty of the clock signal outputted by the voltage-controlled oscillation circuit and the stability of the frequency.

Abstract: To prevent an undesired operating mode of voltage-controlled oscillation (VCO) circuitry from dominating a desired operating mode (e.g., an in-phase operating mode or an out-of-phase operating mode), a supply reset and ramp pulse may be provided to the VCO circuitry when switching to a new mode, such that supply voltage to the VCO circuitry is reset (e.g., set to 0 V or another reference voltage), and gradually increased or ramped up back to a steady-state voltage (e.g., used to maintain a mode) within a time duration. Additionally or alternatively, a switch control bootstrap pulse may be provided to the VCO circuitry that is bootstrapped to (e.g., applied instantaneously or concurrently with) switching the VCO circuitry to the new mode. After a time duration, the VCO circuitry may switch back to a steady-state voltage (e.g., used to maintain the new mode).

Abstract: Technologies are generally described for quadrature-based injection-locking offing oscillators. In some examples, an external signal may be injected into a ring oscillator. Phase signals may be measured from within the ring oscillator and used to determine a mean quadrature error (MQE) that characterizes the difference in frequency between the external signal and the ring oscillator's natural frequency. A control signal may then be generated from the MQE and used to adjust the ring oscillator natural frequency to reduce the difference between the ring oscillator natural frequency and the external signal.
