In a semiconductor device including a plurality of input signal pads (P0, . . . , P7); a plurality of emitter followers (Q01, . . . , Q71) are connected to the input signal pads (P0, . . . , P7); a plurality of input signal buffers (BUF0, . . . , BUF7) are connected to the emitter followers (Q01, . . . , Q71); and a plurality of constant current sources (I01, . . . , I71) are connected to the emitter followers (Q01, . . . , Q71). The emitter followers (Q01, . . . , Q71) are in proximity to the input signal pads (P0, . . . , P7), and the constant current sources (I0, . . . , I7) are in proximity to the emitter followers (Q01, . . . , Q71) . The current values of the constant current sources (I01, . . . , I71 ) are determined in accordance with the length of the corresponding connections between the emitter followers (Q01, . . . , Q71) and the input signal buffers (BUF0, . . . , BUF7). |
