Abstract:
1. An oscillator system, the system comprising: a first voltage-to-current converter configured to convert a first voltage to a first current; a second voltage-to-current converter configured to convert a second voltage to a second current; a first current-mode N-bit digital-to-analog converter configured to receive the second current, a first clock signal and a second clock signal, and to generate a third current, N being a first positive integer, the first clock signal being associated with a first clock frequency corresponding to a first clock period, the second clock signal being associated with a second clock frequency corresponding to a second clock period; and a first current comparator configured to compare the first current to the third current and to generate the second clock signal based on at least a comparison of the first current and the third current; wherein the first current comparator is configured to: wherein the first current-mode N-bit digital-to-analog converter is configured to:
