Abstract
A signal-aligning circuit includes a phase-adjusting circuit, a first control circuit, a second control circuit, and a tuning circuit. The first control circuit outputs a first voltage signal reflecting a phase difference between a first input signal (reference signal) and a second input signal (adjusted signal) and having a static phase offset due to asymmetries in the first control circuit. The second control circuit is a replica of the first control circuit, and receives the reference signal at two inputs thereof and outputs a second voltage signal reflecting the same static phase offset. The tuning circuit compares the first and second voltage signals and tunes a bias current in the first and second control circuits, whereby the static phase offsets of the first and the second control circuits becomes zero when the adjusted signal is phase-aligned with the reference signal in the steady state.
