    Abstract: Successive two-trip traversals of charges between gates G.sub.0 and G.sub.2 make it possible to obtain beneath gates G.sub.1 and G.sub.2 quantities of charges equal to Q.sub.R, Q.sub.R /2, Q.sub.R /2.sup.2 . . . Q.sub.R /2.sup.i. A readout device for reading charges and connected to gates G.sub.2 and G.sub.4 generates voltages V.sub.R and V.sub.Ri =a.sub.0 .multidot.V.sub.R +a.sub.1 .multidot.V.sub.R /2+ . . . +a.sub.i-1 .multidot.V.sub.R /2.sup.i-1 +V.sub.R /2.sup.i which are compared with a voltage sample V.sub.x to be coded in order to determine by successive approximations the coefficients a.sub.0 . . . a.sub.n which are equal to 0 or to 1 such that V.sub.x =a.sub.0 .multidot.V.sub.R +a.sub.1 .multidot.V.sub.R /2+ . . . +a.sub.n .multidot.V.sub.R /2.sup.n. Depending on the value of a.sub.i, each quantity of charges Q.sub.R /2.sup.i stored beneath gate G.sub.1 is removed beneath diode D.sub.e or stored beneath gate G.sub.3 and then transferred beneath gate G.sub.4.

    Abstract: A current supply circuit and a digital analog converter provided with the same are provided to prevent the distortion of an output current caused by changes or ununiformity in a semiconductor process. A current supply circuit includes a corrector(310) and a current source unit(320). The corrector(310) includes a reference current source(ISRC1) and a reference current generator(3010). The reference current generator receives the reference current source to generate reference current. The current source part includes a first switch(SW1), a correction current generator(3020), a second switch(SW2), and a buffer(3000). The first switch is electrically connected with one of the reference current source and an output terminal. The correction current generator generates corrected current in accordance with the reference current generator. The second switch electrically connects the reference current generator and the correction current generator. The buffer is electrically connected between the first switch and the correction current generator.
