Abstract
An oscillator is disclosed that can generate an oscillation signal using a latch and two delay elements. For some embodiments, the oscillator includes an SR latch, a first delay element, and a second delay element. The SR latch has a first input, a second input, a first output, and a second output. The first delay element is coupled between the first output and the first input of the SR latch. The second delay element is coupled between the second output and the second input of the SR latch. For some embodiments, the first and second delay elements include a programmable pull-up circuit that allows the charging current to be adjusted in discrete amounts, and include a programmable capacitor circuit that allows the capacitance value to be adjusted in discrete amounts.
