A method is disclosed for preventing a driver from changing the state of an output switch in response to parasitic oscillation that includes allowing or preventing a signal from the driver from reaching the output switch based on a timing signal. Also disclosed is a way to prevent a driver from changing the state of an output switch in response to parasitic oscillation by using a directional element, a timing element, and a control element. An exemplary oscillator circuit that uses a diode, a MOSFET, and a resistor to prevent parasitic oscillation without adding propagation delay, and a block diagram of circuit functionality, is also disclosed.

A circuit, integrated circuit, and radar system implementing a highly coupled inductor design for a multi-core oscillator is provided. An example circuit may include a plurality of inductors, each inductor including: a first inductor portion and a second inductor portion electrically connected in series. In some embodiments, for each inductor, the first inductor portion may be magnetically coupled to a first or second inductor portion of a first coupling inductor of the plurality of inductors, and the second inductor portion may be magnetically coupled to a first or second inductor portion of a second coupling inductor of the plurality of inductors, where the first coupling inductor and the second coupling inductor are different inductors.

Various embodiments provide apparatuses, systems, and methods for resonant rotary clocking to generate synchronized clock signals. A base die may include a resonant ring structure to form a plurality of rotary traveling wave oscillators (RTWOs) coupled to one another in a rotary oscillator array (ROA). The ROA may provide synchronized clock signals at deterministic phase points that are tapped from the resonant ring structure. Multiple dies may be coupled to the base die (e.g., in a multi-die system) and may receive the tapped clock signals. Other embodiments may be described and claimed.

A quadrature oscillator according to the embodiments herein comprising two pairs of main transistors, two pairs of resonators and two pairs of injection transistors. The quadrature oscillator is split into two halves, which are separated in the chip layout. That is the two pairs of resonators are separated from each other, and the two pairs of the main transistors are separated from the resonator they coupled to such that the quadrature oscillator is separated into two spaced apart oscillator halves connected by transmission lines.
