Patent ID: 7106139

Claim:
An amplification circuit, comprising: a first inverter having a plurality of first gate elements which are formed in a first active region, and an input terminal and an output terminal connected to a feedback resistor, wherein first gate electrodes of the first gate elements extend in a first direction; and a second inverter having a plurality of second gate elements which are formed in a second active region, wherein the second inverter receives an output signal from the first inverter and adjusts a waveform of the output signal, wherein second gate electrodes of the second gate elements extend in the first direction, wherein a gate length of all of the first gate electrodes is the same as a gate length of all of the second gate electrodes, and a gate width of all of the first gate electrodes which is defined by the first active region, is the same as a gate width of all of the second gate electrodes which is defined by the second active region.
