Abstract:
An apparatus is disclosed that implements a phase-locked loop (PLL) that uses multiple error determiners as part of a feedback loop. In an example aspect, an apparatus for generating a frequency includes a PLL. The PLL includes a loop filter, a voltage-controlled oscillator (VCO), a frequency divider, and multiple error determiners. The loop filter includes a filter input node and a filter output node. The VCO includes a VCO input node and a VCO output node. The VCO input node is coupled to the filter output node. The frequency divider includes a divider input node and multiple divider output nodes. The divider input node is coupled to the VCO output node. The multiple error determiners are coupled between the multiple divider output nodes and the filter input node.
