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