Power source circuit for generating positive and negative voltage sources |
摘要 |
A power source circuit for a flash memory includes a positive circuit section for generating a positive voltage source, a source follower transistor for converting the impedance of the first voltage source, a negative circuit section for generating a negative voltage source while maintaining a voltage difference between the output of the source follower transistor and the negative voltage source at a first reference potential. The positive circuit section includes a voltage compensating transistor having a threshold voltage equal to the threshold of the source follower transistor.
