SEMICONDUCTOR INTEGRATED CIRCUIT |
摘要 |
<p>A semiconductor integrated circuit is characterized in that it comprises analog macros each having a comb capacitor (10), each comb capacitor (10) is composed of comb-shaped electrodes (11, 12), the comb tooth portions (13) of the electrode (11) and the comb tooth portions (14) of the electrode (12) are so interdigitized that the comb tooth portions (13) and the comb tooth portions (14) are alternated and parallel to one another, and the tooth portion intervals (S) are varied according to the absolute accuracy indicating the difference between the actual capacitance and the ideal capacitance or the relative accuracy indicating the differencebetween the capacitances of the adjacent comb capacitors. A high-accuracy analog macro comprising a comb capacitor whose high capacitance accuracy is ensured and a semiconductor integrated circuit comprising highly-integrated analog macros are provided.</p> |
