ABSTRACT:
A parallel trimming method and apparatus are provided for a voltage controlled delay loop. A plurality of delay units in a voltage controlled delay loop are trimmed. Each delay unit comprises a delay element and a latch buffer. A reference signal is applied to each of the delay units and a position of an edge (such as a rising or falling edge) associated with each of the delay units is identified. The edges of the delay units are then aligned by adjusting a trim setting of the respective latch buffer.
