Title: High speed input buffer circuit for low voltage interface
Inventor: LIM KYU-NAM
IPC: H03F3/45
Filed: 2000-05-04
Granted: 2002-09-11
Abstract: An input buffer circuit which simultaneously supports a low voltage interface and a general low voltage transistor-transistor logic (LVTTL) interface and which operates at high speed is provided. In the input buffer circuit, a self bias voltage generated by a self biased differential amplification circuit is used not only for tracking a common mode input voltage in the differential amplification circuit but also for controlling the current of a current source for supplying current to the differential amplification circuit and a current sink for sinking current from the differential amplification circuit. Accordingly, it is possible to maintain the self bias voltage to be substantially uniform. Therefore, the entire transconductance gain gm of the differential amplification circuit is substantially uniform regardless of the change in a reference voltage input to the differential amplification circuit. As a result, a low voltage interface characteristic is improved. Also, the input buffer circuit further includes a swing width control circuit for preventing the swing width of the output signal of the differential amplification circuit from becoming excessively large, in response to the inverted signal of the output signal of the differential amplification circuit. Accordingly, skew is reduced, to thus improve the operating speed of the input buffer.
