A receiver stage for receiving a receive signal comprises M receiving paths, each receiving path comprises a signal processor and K comparators. The signal processors of the M receiving paths are configured to generate, for each of the M receiving paths, an amplified version of the receive signal, such that an amplification gain of the respective receiving path increases from a first of the M receiving paths to a last of the M receiving paths. For each of the M receiving paths the K comparators of the respective receiving paths are configured to compare the amplified receive signal of the respective receiving path with a respective threshold value. For each of the M receiving paths the threshold value increases from a first of the K comparators to the last of the K comparators.

Receiving stage and method for receiving

A receiver for receiving an RF signal transmitting a bit sequence representing a symbol is provided. The receiver includes an oscillator, a counter, at least one state machine and at least one correlator. The oscillator is configured to oscillate dependent on the received RF signal, wherein the oscillator signal is controlled to provide an oscillation signal based on the oscillation during a plurality of subsequent active periods. The counter is configured to provide a counter value describing threshold crossings of the oscillator signal for each of the active periods. The at least one state machine is connected to the counter and configured to output state values, each state value dependent on two subsequent counter values. The at least one correlator is configured to correlate the output state values with a predefined bit sequence and to output a value representing the symbol dependent on the correlation.
