H03L1/025 - CPC Classification

Classification description:

Stabilisation of generator output against variations of physical values, e.g. power supply against variations of temperature only by indirect stabilisation, i.e. by generating an electrical correction signal which is a function of the temperature by using voltage variable capacitance diodes and a memory for digitally storing correction values
