Abstract
The invention proposes a sampling phase detector in which a first sampling transistor with a very high sensitivity determines the phase of a signal to be sampled. A signal representative of the phase is supplied to a second sampling stage. The second sampling stage retains the phase value determined in this way. The invention provides a phase signal that is more stable and more sensitive. The invention also provides a method and an oscillator employing the method.
