    Abstract: Modulation circuitry is configured to generate a phase modulated signal having an output frequency that corresponds to a local oscillator (LO) signal divided by N.5. A phase locked loop (PLL) is configured to generate an LO signal having a frequency that is N.5 times the output frequency. Pulse circuitry configured to generate, based at least on a value of N, an edge signal including a pulse aligned with a positive edge of the LO signal and a pulse aligned with a negative edge of the LO signal. The edge signal is used to generate the phase modulated signal.

    Abstract: A digital to time converter (DTC). The DTC includes a lookup table, a divider, a thermometric array and a switched capacitor array. The lookup table is configured to generate one or more corrections based on thermometric bits of an input signal. The divider is configured to generate a plurality of divider signals from an oscillator signal based on the one or more corrections. The thermometric array is configured to generate a medium approximation signal from the plurality of divider signals based on the one or more corrections. The switched capacitor array is configured to generate a digital delay signal from the medium approximation signal based on the one or more corrections and switched capacitor bits of the input signal.
