Title: Semiconductor multi-stage amplifier
Inventor: ISHIWATARI HIDEYUKI
IPC: H01L27/092
Filed: 1991-03-13
Abstract: PURPOSE:To improve the efficiency by selecting the size of a controlled electrode of an (n+1)th stage semiconductor element to be nearly a multiple of 1/2 power of a gain per stage with respect to the size of an controlled electrode of an n-th stage of semiconductor element ((n) is a natural number being one or over and N-1 or less) in N stages of semiconductor elements connected in cascade (N is a natural number being two or over). CONSTITUTION:For example, FETs Q1-Q3 are employed to form a three-stage amplifier. Let gate width of a FET of each stage be Wg1, Wg2, Wg3, intercept points be P1p1, P1p2, P1p3, consumed power be Pd1, Pd2, Pd3, and the entire intercept point and the consumed power be respectively P1p1, Pd2 in each stage, then the gain of each stage is constant (G(dB)=5(dB) and the intercept and the consumed power of each stage are proportional to the gate width of each stage. Thus, a high linearity is obtained by maximizing a ratio P1p1/Pd1 of the point P1p1 and the power Pd1 determining ternary intermodulation distortion and the requirement of a high efficiency is attained.
