HIGH SPEED RECEIVING CIRCUIT SATISFYING A MOBILE INDUSTRY PROCESSOR INTERFACE STANDARD

摘要

PURPOSE: A high speed receiving circuit is provided to improve a duty ratio of the final output signal by increasing a voltage gain with regard to an input pair of a low voltage level using an analog voltage amplifier. ;CONSTITUTION: An analog voltage amplifier(10) outputs a differential output voltage pair(V1,V2) with regard to an input pair(INN,INP) by using an analog voltage. The analog voltage amplifier uses the analog voltage for securing a voltage headroom. The analog voltage amplifier is comprised of a first amplifier and a second amplifier. A digital voltage amplifier(20) outputs a single output voltage from the differential output voltage pair by using a digital voltage. A buffer(30) amplifies the single output voltage outputted from the digital voltage amplifier to the level of the digital voltage and outputs the amplified single output voltage.;COPYRIGHT KIPO 2011
