Abstract
A semiconductor system and a method for operating the semiconductor system are provided. The semiconductor system comprises a duty cycle corrector (DCC) and an analog quadrature error corrector (QEC). The DCC is configured to receive an input clock signal to adjust a duty cycle of the input clock signal and generate a first modified clock signal. The analog QEC is configured to receive the first modified clock signal. The analog QEC is configured to adjust a delay of the first modified clock signal and generate a first output clock signal and a second output clock signal. The second output clock signal delays or advances a quarter of period from the first output clock signal. The analog QEC comprises a first inverter chain, a phase error detector (PED) and a first low-pass filter (LPF).
