In this letter, we propose a new approach to the design of a digital phase-locked loop (DPLL) with a finite impulse response (FIR) structure, deadbeat property, and H performance. This DPLL is called the deadbeat H FIR DPLL (DHFDPLL). The proposed DHFDPLL ensures the H performance against incorrect information on noise and has intrinsic robustness against quantization effects because of the FIR structure. Demonstrative simulations are provided to show that the DHFDPLL exhibits excellent robustness against effects of incorrect noise and quantization compared with the existing DPLLs.
