Document Type and Number:
Japanese Patent JPS6124666
Kind Code:
B2
Abstract:
A semiconductor temperature compensation circuit for an electronic timepiece is provided. The temperature compensation circuit is characterized by a temperature detection circuit comprised of MOS transistors, at least two of which have distinct conductive coefficients for producing signals representative of variations in ambient temperature and a temperature signal converting means including MOS transistors for converting the temperature dependent signal into a temperature compensation value for effecting timing rate adjustment in an electronic timepiece. The temperature detection circuit and the temperature signal converter circuit are both formed of elements that can be monolithically integrated into the same substrate.
