A dynamic clock skew compensation circuit technique for low power clock distribution

Clock tree synthesis (CTS) is an essential technique for SoC design. A dynamic skew compensation technique is proposed here, which relaxes the CTS requirements and contributes to both small skew and low power operation. A test chip has been fabricated using 0.13-/spl mu/m CMOS technology. Measured results show a 44% skew improvement from a 100-ps initial skew. This technique can be easily implemented in the current CTS flow.
