Application of combining circuit in signal transmission system 合成電路在信號傳輸系統(tǒng)中應(yīng)用
The input of traditional ac-dc converter is diode-capacitance combined circuit . it ? input current wave presents pulse shape, and the power factor ( pf ) on ac line side is low 傳統(tǒng)的ac?dc開關(guān)變換器輸入端是二極管整流-濾波電容組合電路,其輸入電流波形呈脈沖狀,交流網(wǎng)側(cè)功率因數(shù)很低。
This becomes increasingly critical as systems are being designed to combine circuits operating at lower power ( implying higher impedance levels ), higher speed ( implying lower nodal stray capacitance, faster edges, and higher frequencies ), and higher resolution ( much less output noise permitted ) 當(dāng)今的電子系統(tǒng)常常包含著低功耗(意味著阻抗更高)、高速度(節(jié)點(diǎn)寄生電容更小、信號邊沿更陡峭、信號頻率更高)和高分辨力(噪聲容限更?。┑入娐罚虼诉@個(gè)問題尤其應(yīng)該引起重視。
