A signal level detect circuit configured to assess an input signal with varying amplitude signal levels and to generate an indicator signal includes an input circuit configured to receive the input signal and to process the input signal, the input circuit including a first node on which the input signal is sampled; a comparator configured to compare the processed input signal to a signal level threshold and generate a comparator output signal; and an active discharge circuit configured to provide a first discharge current to the first node in response to the comparator output signal. The comparator output signal changes from a low output state to a high output state in response to the comparator input signal, and the active discharge circuit generates the first discharge current to discharge the sampled input signal on the first node after the comparator output signal changes to the high output state.
