Abstract
A polyphase filter operates to provide capacitive compensation to drive a multiphase network for generating quadrature signals. The polyphase filter can include a capacitive compensation mechanism at internal nodes. The capacitive compensation mechanism includes a first phase lag circuit between a first internal node and a second internal node and a second phase lag circuit coupled between a third internal node and a fourth internal node. The first internal node is coupled to the second internal node via a first inductor coupled to a first resistor, the second internal node is coupled to the third internal node via a second inductor coupled to a second resistor, the third internal node is coupled to the fourth internal node via a third inductor coupled to a third resistor, and the fourth internal node is coupled to the first internal node via a fourth inductor coupled to a fourth resistor.
