Layout design method for N-channel field effect transistor array in CMOS technique

The invention provides a layout design method for an N-channel field effect transistor array in a CMOS technique. A P pitfall doped area is formed below a shallow groove used in an N-channel field effect transistor, and the width range of the shallow groove is between 0.25 mu m and 0.31 mu m. The method provided by the invention can manufacture the shallow groove with good isolation performance and narrow width, and can reduce the leakage current of the N-channel field effect transistor, thus the performance of a component is improved, and the N-channel field effect transistor array with higher layout density also can be manufactured.

Air conditioner frequency-conversion driving control system and air conditioner using same

The invention discloses an air conditioner frequency-conversion driving control system and an air conditioner using the same. The air conditioner frequency-conversion driving control system comprises a compressor motor, a fan motor and a single frequency-conversion driver. An output shaft of the frequency-conversion driver is simultaneously connected with the compressor motor and the fan motor, so that the compressor motor and the fan motor are simultaneously controlled. The control cost is greatly reduced on the premise that the running efficiency and the energy efficiency ratio of the air conditioner frequency-conversion driving control system are equivalent to those of a double-frequency-conversion air conditioner driving system, and the mounting size of the air conditioner frequency conversion system is effectively reduced.
