摘要:
A folder common cascode circuit with symmetric parallel signal paths from the differential inputs to the differential outputs provides a low skew, low jitter, low power differential amplifier. The signal paths on either side of the differential amplifier are made equal with equal loads along each path. Pairs of complementary NMOS and PMOS transistor pairs with parallel complementary biasing stacks on the output cascode circuitry maintain symmetrical parallel signal paths, amplification and impedance loading from differential input to differential output. Output voltage translating inverters provide a higher voltage level output signal while maintaining low skew and jitter.
