A arrangement is disclosed for an on-chip system having an increased resolution for supply voltage measurements. The system includes a phase locked loop (PLL), a divider, and a timer. The PLL is configured to generate an oscillator signal. The divider is configured to divide the oscillator signal to generate an divided clock signal. The timer is configured to generate an application start signal and an analog to digital converter (ADC) start signal based on the oscillator signal and a timer delay (Tdelay). The timer delay (Tdelay) is based on the application start signal and the ADC start signal.
