Abstract
A method and an apparatus () for generating corrected quadrature phase signal pairs in a communication device are provided. The apparatus () includes a quadrature phase generator (), programmable delay elements () and a control circuit (). The programmable delay elements () receive a quadrature phase signal pair (signals Iand Q) from the quadrature phase generator (). The control circuit () generates a control signal () based on outputs () of the programmable delay elements (). The control signal () configures the programmable delay elements (). The programmable delay elements () are configured to adjust delay between the signals I () and Q (). The programmable delay elements () are also used to adjust duty cycle for the quadrature phase signal pair to provide the corrected quadrature phase signal pair.
