目前,CMOS电路的特点主要是以低保持电流、低功耗为主,在广泛的VLSI领域中,NMOS电路占主要地位。然而,仅从1981年国际固体电路会议上所发表的NMOS微型计算机来看,HP公司的NMOS电路功耗为7W,还有英特尔公司的3芯片结构,每个芯片的最大功耗为2.3W,尽管考虑到管壳的散热技术,可以说也有一定的限度。一般来说,流经NMOS E/D电路的电流I_L在通导时可 At present, CMOS circuits are mainly characterized by low holding current and low power consumption. In a wide range of VLSI fields, NMOS circuits dominate. However, only from the NMOS microcomputers released at the International Solid State Circuits Conference in 1981, HP’s NMOS circuit consumes 7W, and Intel’s 3-chip architecture, with a maximum power consumption of 2.3W per chip, Although taking into account the cooling technology shell, it can be said that there are certain limits. In general, the current I_L flowing through the NMOS E / D circuit is conductive
