Abstract
A method and a circuit for the digital correction of a frequency of a signal, especially for use in a transmitter/receiver circuit include rotating a signal 'pointer' (i0, q0) using a CORDIC algorithm, through a predetermined angle in a complex I/Q plane corresponding to a correction frequency. The CORDIC algorithm includes micro-rotation blocks corresponding to N stages, and a character table and a register.
