Abstract: A complementary metal oxide semiconductor (CMOS)-to-current mode logic (CML) converter for converting a CMOS input signal into a CML output signal, including: a low-pass filter comprising a fixed resistor and a first fixed capacitor, and a swing width control circuit configured to adjust a swing width of a voltage swing of the CML output signal based on a common mode level, wherein the swing width control circuit includes: a second fixed capacitor; and a variable capacitor comprising a capacitor array.
