Patent Searching and Data


Title:
【発明の名称】温度、供給電圧及びトランジスタの製造品質に無関係なCMOS出力増幅器
Document Type and Number:
Japanese Patent JP2002521906
Kind Code:
A
Abstract:
The invention relates to a circuit of which the operating rate varies according to temperature, supply voltage and intrinsic quality of the transistors of the circuit, associated to a compensating circuit which comprises a constant current source (26) that produces a substantially constant current which is independent of temperature, supply voltage and intrinsic quality of the transistors of the circuit, a variable current source (28) producing a current that increases in an inverse proportion to temperature, supply voltage and intrinsic quality of the transistors of the circuit, and means for decreasing the operating rate of the circuit when the difference of the currents produced by the first and second sources increases.
