Differential comparator for amplifying small swing signals to a full swing output |
摘要 |
A differential comparator that amplifies small swing signals to full swing signals. The differential comparator comprises a current switch having a pair of inputs coupled to receive a pair of small swing complementary input signals and a pair of complementary outputs that output complementary signals. The complementary signals output by the current switch have a voltage swing that centers about a predetermined voltage in response to the complementary input signals. The differential comparator further comprises first and second inverters coupled to receive the output complementary signals, wherein each inverter has a trip point voltage equal to the predetermined voltage. The first and second inverters output full swing complementary output signals in response to the complementary signals output by the current switch.
