Abstract:
A Digital-to-Time (DTC) for a Digital Polar Transmitter (DPT) comprises a coarse delay/phase segment and a fine delay/phase segment. The coarse delay/phase segment generates an even delay/phase signal and an odd delay/phase signal. The fine/phase delay segment receives the even coarse phase signal and the odd coarse phase signal, and is responsive to a fine delay/phase control signal to generate a fine delay/phase output signal that is an interpolation of the even delay/phase signal and the odd delay/phase signal. In one exemplary embodiment, the fine delay/phase control signal comprises a binary signal having 2N values, and the fine delay/phase segment comprises 2N interpolators. Each interpolator is coupled to the even and odd coarse phase signals and is controlled by the fine delay/phase control signal to be responsive to the even coarse phase signal or the odd coarse phase signal based on a value of the fine delay/phase control signal.
