Claim 11:
12. The circuit of claim 11, wherein the comparator circuit further includes:
a first transistor having a first current electrode coupled at the first voltage supply terminal and a second current electrode and control electrode coupled at a second node, the second node configured as a second bias voltage output of the second bias circuit;
a second transistor having a first current electrode coupled at the second current electrode of the first transistor and the second node, a second current electrode coupled at the first node, and a control electrode configured as a first comparator input to receive the level-shifted version of the first bias voltage;
a third transistor having a first current electrode coupled at the first voltage supply terminal, a second current electrode coupled at the comparator output, and control electrode coupled at the second node; and
a fourth transistor having a first current electrode coupled at the comparator output, a second current electrode coupled at the first node, and a control electrode configured as a second comparator input to receive the level-shifted version of the first oscillator signal.
