Abstract
In an embodiment, a circuit includes cascaded delay units arranged in a chain, each delay unit having an input-to-output delay time, wherein a first delay unit in the chain is configured to receive an input signal for propagating along the delay units in the chain, logic circuitry coupled to delay units in the chain, the logic circuitry configured to generate a clock signal as a logic combination of signals input to and output from the delay units in the chain and feedback circuitry configured to supply to the first delay unit in the chain a feedback signal, the feedback circuitry including a first feedback signal path from a last delay unit in the chain to the first delay unit in the chain and a second feedback signal path from an intermediate delay unit in the chain to the first delay unit in the chain, the intermediate delay unit arranged between the first delay unit in the chain and the last delay unit in the chain.
