Abstract
The present disclosure generally pertains to time-of-flight demodulation circuitry, configured to: apply, for a predetermined time period, a first modulation signal to a first signal path including a first light detection element; apply, for the predetermined time period, a second modulation signal to a second signal path including a second light detection element; and after the predetermined time period, transfer the first modulation signal from the first signal path to the second signal path and transfer the second modulation signal from the second signal path to the first signal path.
