CONSTITUTION:As weighing resistors 201-206, R, 2R, 2<2>R, 2<3>R, R, and 2<4>R are used. The resistors are shorted by metallic wiring links 10. Since the (n)th resistance is 204, (n) becomes 4. Therefore, 2<2>R, which is the third resistor from the (n/2+1)th resistor, is used as the unit resistor. Namely, the resistor 203 is one piece. Since 202 is one half the resistor 203, two resistors each having the same pattern as that of the resistor 203 are connected in parallel. Two unit resistors are connected in series in the 204. Four unit resistors are connected in parallel in the 205 as well as in the first resistor group 201. All together, 13 resistors are formed. Meanwhile, the value of the 206 is equal to the total value of 201-205. When the value is converted to the value of the unit resistor 203, the series resistance value of four pieces is obtained. Therefore, the 206 can be formed by four pieces. Therefore, the device is completed by 17 unit resistors in all.

Abstract: PURPOSE:To obtain a pulse generating circuit of low power consumption by using a part of a drive circuit of plural capacitive loads such as piezoelectric elements over >=2 channels in common so as to simplify the circuit constitution without losing the high speed performance of the drive circuit. CONSTITUTION:When all input terminals 41-43 are at an L level, all the 1st switches 11-13 are turned off, the 3nd switch 2 is turned on by an output of a NOR circuit 9 and capacitive loads 81-83 such as piezoelectric elements are charged via buffer devices 31-33. When the input terminal 41 goes to an H level, the 2nd switch 2 is turned off, the electric charge of the load 81 is discharged and this state is repeated further. Thus, a voltage pulse where the level of an output terminal changes from H L is obtained by the change of the input signal level from L H and the constitution is simplified by using in common a part of the drive circuit of the >=2 capacitive loads.
