    摘要: A digital temperture compensation oscillator for digitally compensating a variation in oscillation frequency due to temperatures, by applying a compensation voltage to a voltage controlled oscillator, comprises temperature detection means, A/D conversion means, memory means, operation means and D/A conversion means. The temperature detection means detects temperatures when the voltage controlled oscillator is operated, and generates a temperature signal. The A/D conversion means receives the temperature signal, digitizes the temperature signal, and generates digital temperature data. The memory means stores compensation data corresponding to the compensation voltage as difference data at corresponding addresses. The difference data includes, when N-stage level difference data (N=a positive integer) are utilized, predetermined reference values of 0th difference data to (N-1)-th difference data of the compensation data and all N-th difference data. The operation means receives the digital temperature data and the difference data, and generates the compensation data on the basis of the difference data in response to the digital temperature data. The D/A conversion means receives the compensation data, converts the compensation data into an analog compensation voltage, and supplies the analog compensation voltage to the voltage controlled oscillator.
