It consists of a phase precision regulator and a frequency divider. The phase precision regulator generates two programmable currents by controlling the conduction of the tail current sources and then changes the currents into two bias voltages which are superimposed on the clock signals to adjust the phase difference of the four quadrature signals generated by the frequency divider, making the phase difference of 90 degrees. The four quadrature signals\u2019 generator with precise phase modulation has been implemented in a 0.18\u2009<jats:italic>\u03bc<\/jats:italic>m mixed-signal and RF 1P6M CMOS technology.
