IPC: G01R27/28
Filed: 1983-06-22
Abstract: PURPOSE:To exert no influence on others whichever is set, by providing the fourth circuit for generating a phase setting signal by inputting a signal of the first and the third circuits, and the fifth circuit for generating a variable phase output signal by inputting the second and the fourth circuits. CONSTITUTION:A frequency fi1 set by a frequency setting part 1 is outputted from a frequency oscillating part 2, and this frequency is divided by a frequency circuit 10, becomes fi2 and is outputted. A phase signal generating part 5 generates an output pulse following a set value of a phase angle setting device 4. Also, an input of a counter circuit 6(1) is only a frequency input of fi2, therefore, generates an output to a zero detecting circuit 7. The phase signal generating part 5 starts a count of an input frequency of fi1, and when it conforms with an output value of the phase setting part 4, a zero resetting signal is outputted to a counter circuit 6(2). As a result, the counter circuit 6(2) executes a motion governed by an output pulse of the phase signal generating part 5. Accordingly, the input frequency of fi2 executes a function for only sending said signal as an address signal to an ROM8(2), and becomes a motion of a variable phase outputting circuit.

Filed: 1988-05-07
Abstract: PURPOSE:To facilitate the design and to reduce the manufacture cost by constituting a 2nd transistor(TR) by n-set of TRs of the same structure as a 1st TR. CONSTITUTION:The 2nd TR 11 consists of n-set of TRs of the same structure as the 1st TR 10. Thus, the gate width Wg2 of the 2nd TR 11 is selected to be a multiple of (n) of the gate width Wg1 of the 1st TR 10 and a current flowing to the 2nd TR 11 depends on the gate width Wg2 and since the gate width Wg2 is a multiple (n) of the gate width Wg1, the object current being a multiple of (n) is obtained accurately. Thus, the mask design is facilitated. Even if the process condition is changed, since it is not required to modify the mask, the cost is reduced.
