    摘要: The present invention relates to an integrated circuit manufacturing method for producing a double-diffused metal-oxide-semiconductor (DMOS), which utilizes a removable spacer method with a self-aligned channel to manufacture an improved DMOS with a reduced parasitic capacitance, and a high-resistance DMOS for a high power application can thus be fabricated also. Via the present invention, a faster switch with more usable operating frequencies can be achieved.

    摘要: A method of suppressing generation of carrier leak in a transmitter and reducing deterioration of communication quality comprises the steps of outputting DC elements (I, Q) from a DSP gradually changing the voltage values, measuring a sum of the DC elements (.DELTA.I.sub.DC, .DELTA.Q.sub.DC) and DC elements (I, Q), storing the DC elements (I, Q), when the above sum is equal to a specified value (herein, 0 V), as DC elements -.DELTA.I.sub.DC, -.DELTA.Q.sub.DC for correction, and correcting the DC elements (I.sub.DC, Q.sub.DC) (DC elements obtained by amplifying DC elements for (I, Q) channels demodulated by a quadrature demodulator during transmission) using the DC elements (-.DELTA.I.sub.DC, -.DELTA.Q.sub.DC) for correction during transmission.
