Abstract
The techniques described herein relate to digitally controlled delay line gain calibration using error injection. An example apparatus includes a digitally controlled delay line (DCDL) with a DCDL output and configured to: receive a clock signal to be output from a voltage-controlled oscillator, and delay the clock signal to generate a first delayed clock signal. The apparatus further includes an error injection circuit with a first error injection input and a second error injection input, the first error injection input coupled to the DCDL output. The apparatus additionally includes a phase controller with a phase controller output coupled to the second error injection input, the phase controller configured to, in response to a pseudorandom binary sequence signal, instruct the error injection circuit to generate a second delayed clock signal based on a delay of the first delayed clock signal.
