Claims20
A peak detector comprising:
- an asymmetrical latch having a first input and a second input;
- and
- a CMOS converter having a first input coupled to a first output of the asymmetrical latch, a second input coupled to a second output of the asymmetrical latch, and an output.
A method comprising:
- amplifying a differential input signal to provide an amplified differential signal;
- asymmetrically latching the amplified differential signal to provide a latched differential signal;
- and
- converting the latched differential signal into a CMOS-level output signal.
1 more element
