摘要： Electrically conductive layers 1a and 2a connected to each other via a contact form one inductor, while electrically conductive layers 1b and 2b connected to each other via other contact form the other inductor. Since the areas defined by the loops forming these two inductors are equal to each other, the inductances of the inductors are also equal to each other. Between both the inductors, the lengths in the loop of the portions (the conductive layers 1a and 1b) formed on a lower interlayer insulating film are equal to each other, while the lengths in the loop of the portions (the conductive layers 2a and 2b) formed on an upper interlayer insulating film are also equal to each other. This allows external disturbances such as parasitic capacitance to affect both the inductors equally. Accordingly, a voltage controlled oscillator incorporating the invention can stably provide undistorted sinusoidal oscillation signals.

摘要： A semiconductor device comprising at least two pinch resistors or two ion-implanted resistors having a precise resistance ratio therebetween. The pinch resistor and ion-implanted resistor have at least one region contributing to the determination of a resistance value, respectively. In two pinch resistors or two ion-implanted resistors, a ratio in number of a plurality of regions in one resistor to at least one region in the other resistor is selected to be identical to the resistance ratio of one resistor to the other resistor, resulting in that a precise resistance ratio is realized despite different configurations of the two resistors.

摘要： A rotation speed control circuit is designed to control the rotational speed of a motor at a constant speed, despite variations in both the load and the power supply. A motor (100') and a resistor (R) are connected to a power supply terminal, respectively. A control circuit (200') receives an operation voltage from the resistor R and supplies an output to the other end of the motor (100'). Within the control circuit (200'), the operation voltage is supplied to one end of a comparator (10) through a constant voltage generator (9), and the output is supplied to the other end of the comparator (10) through a resistor (R.sub.11). A output circuit (11) supplies currents both to the motor (100') and to the resistor (R), respectively, in response to the output of the comparator (10).

摘要： A motor driving circuit capable of controlling a motor speed by a current controlled method using negative impedance is constituted by a constant-current circuit, a reference voltage generating circuit, a comparator circuit, an output driving circuit, a symmetric current circuit, and a switching circuit. The reference voltage generating circuit outputs a voltage of a value derived from addition of a reference voltage and a voltage proportional to a value of a current flowing to a motor. The comparator circuit compares a voltage outputted from the reference voltage generating circuit and a voltage at an output terminal. The output driving circuit amplifies an output of the comparator circuit. The symmetric current circuit amplifies the output from the output driving circuit. The switching circuit performs switching of connections of one of transistors in the symmetric current circuit between the input of the reference voltage generating circuit and the output terminal, and can release the motor from a normal state of operation upon starting the motor. Thus, it is possible to achieve sufficient torque during the starting operation of the motor.

A voltage consisting of the sum of a reference voltage and a voltage generated across the resistor by the first output current of the current mirror circuit is applied to the first input terminal of the first voltage comparator. The second output current of the current mirror circuit is fed to the motor and to the second input terminal of the first voltage comparator. A second comparator detects the voltage difference between the first and second input terminals of the first voltage comparator. The output of the second comparator is applied to the current mirror circuit to enhance the starting torque of the motor.
