Abstract
A clock signal generator, including: an in-phase clock generating circuit, comprising: an inverter configured to invert an input clock signal to generate a substantially square wave voltage; and a first transimpedance amplifier (TIA) configured to generate an in-phase clock signal based on the substantially square wave voltage; and a quadrature-phase clock generating circuit comprising: a load capacitor; a switched integrator configured to integrate the input clock signal to generate a substantially triangular wave voltage across the load capacitor; and a second transimpedance amplifier (TIA) configured to generate a quadrature-phase clock signal based on the substantially triangular wave voltage.
