Classification: CPC H  G | IPC G  H

Claim 12:
13. A detector circuit, comprising:
a comparator configured to generate an output based on a comparison of a reference voltage to a trigger voltage;
a compensation circuit comprising at least one compensation transistor configured to compensate for at least one process variation of the comparator; and
a plurality of charge pumps each configured to generate a pre-charge voltage and a boost voltage, wherein each of the plurality of charge pumps is configured to output the pre-charge voltage in response to a first signal and the boost voltage in response to a second signal,
wherein the comparator comprises:
a positive reference system including a PMOS current source and a PMOS pass-gate;
a negative reference system including an NMOS current source and an NMOS pass-gate; and
a transistor coupled between a pump output voltage input and at least one of the PMOS pass-gate and the NMOS pass-gate.
