摘要:
Some embodiments of the invention relate a circuit having a first and a second electrically connected voltage domains, respectively biased at different supply voltages (e.g., the first voltage domain biased at a low bias voltage and the second voltage domain biased at a second, different supply voltage). The apparatus further comprises a first DC current source coupled to one of the voltage domains (e.g., the first voltage domain having a low DC voltage potential) and a second DC current source coupled to the other voltage domain (e.g., the second voltage domain having a high DC voltage potential). The first and second DC current sources are configured to provide a DC cancellation current having a value that cancels a DC current generated by the potential difference between the first and second voltage domains.
