Programmable impedance control circuit |
摘要 |
Disclosed is a programmable impedance control circuit, comprising a voltage divider, the voltage divider comprising an MOS array supplied with a first voltage and an external resistance having an external impedance equal to N times said external resistance. The voltage divider outputs a second voltage. A reference voltage generator is provided for generating a third voltage corresponding to N/(N+M) times said first voltage as a reference voltage for said second voltage, and wherein M times internal impedance is used for N times external impedance (N=M or N<>M).
