IPC: H03B5/32
Filed: 1987-04-21
Abstract: PURPOSE:To reduce the number of components, to attach high vibration resistance, and to improve frequency stability for a long time, by fetching a variable capacitor in an integrated circuit, and performing dispersion on a capacitance value at a nonvolatile memory. CONSTITUTION:All of capacity cells Cm, n are provided with the same capacity values and the same circuits. By setting the characteristic of data for the address of the nonvolatile memory 103 so as to be a specific function, the change of a frequency for the address can be formed linearly. When an oscillation period T is set at relation T=f(CG) for a gate capacity, linearity with a ratio of one to one can be obtained adversely by programming relation CG=g(T) as the data of the nonvolatile memory. For example, assuming that temperature compensating data are set as 40 points of 0-40 deg.C with a unit of 1 deg.C, the rows of the nonvolatile memory go to 40 rows. Therefore, a memory cell is constituted of 40X6=240 bits.
