Title: Sample and hold circuit
Inventor: MURAYAMA AKIHIRO
IPC: H03K7/02
Filed: 1987-04-28
Abstract: PURPOSE:To obtain the optimum value of current consumption corresponding to the difference of input/output potential, by inputting the first and second output currents of a differential pair circuit, and controlling the charging/discharging current of a capacitor corresponding to the differential current of both output currents. CONSTITUTION:At the time of sampling, the active state of a current amplifier circuit is generated by connecting a second constant current source I2 to the current amplifier circuit by a switch device W, and first and second currents outputted from the differential pair circuit corresponding to the differential voltage between an input voltage and the charging voltage of the capacitor are inputted to the current amplifier circuit. And a current difference is detected by the current amplifier circuit, and by amplifying the current difference, the charging/discharging current amplitude of the capacitor is controlled. In such a case, since the charging/discharging current amplitude is changed corresponding to the differential voltage between the input voltage Vin and the charging voltage of the capacitor, the current consumption can be reduced. Also, it is possible to reduce the current consumption further by decreasing the output current of the second constant current source I2, that is, the bias current of the current amplifier circuit. In such a way, the optimum value of the current consumption corresponding to the difference of the input/output potential can be obtained.

Filed: 1980-07-31
Abstract: PURPOSE:To correct the tape positioning error and realize a writing retrial, by measuring the degree of the positioning error on a reading survo track on a trailing servo track during a retrial of writing action and driving the tape in the direction where the degree of detection is reduced for the servo track error. CONSTITUTION:A writing retrial deciding circuit 11 decides that a rewriting instruction has been given by monitoring an upper controller interface. For execution of this instruction, a positioning error detecting circuit 6 gives the degree of positioning error obtained by reading and measuring both the reading servo track and the trailing servo track to an otimum reproduction positioning deciding circuit 12 and calculates the degree of error for the position of a magnetic tape from the degree of positioning error and based on the prescribed optimum reproduction positioning logic to apply it to a step feed extent control circuit 7. After this, D/A converter 8, a power amplifier 9, a capstan motor 10 and a writing control circuit 13 work in that order to correct the position of the magnetic tape. Thus the tape writing never fails during a retrial even to the factor of error such as the single-side extension of tape.

Title: Comparator
Inventor: RYU KAZUO
IPC: H03M1/38
Filed: 1990-04-20
Abstract: PURPOSE:To attain accurate comparison by giving a reference voltage with an input offset voltage added thereto as a reference voltage of a differential amplifier so as to compensate the input offset voltage. CONSTITUTION:Switches 7, 10 are closed for the sampling period of an input signal VA1. Thus, a constant voltage VB is fed to the noninverting input terminal of a differential amplifier 6 and a voltage being the sum of the constant voltage VB and an input offset voltage VOFF by the action of a negative feedback amplifier is applied to an inverting input terminal. Thus, a reference voltage including an input offset voltage is applied to the inverting input terminal of the differential amplifier 6 functioning as a comparator for the comparison period receiving a 2nd input signal VA2 and a comparison output whose input offset is compensated is obtained. Thus, the voltage gain is increased and the operation is made stable against the fluctuation of the power supply voltage and the influence of the input offset voltage is eliminated and accurate comparison is attained.
