Current scaling dac
WebThe output voltage, Vout, of an n-bit current scaling DAC with reference voltage Vref and resistor R . can be expressed as: Vout ) 2 ^ n x I€ x R / 2^6 -1 x Vref. where Iine is the input current that corresponds to the digital input code. In this case, n = 6, Vref = 1V, and R = 10K. Therefore, the output expression for the DAC is: WebCharge scaling DACs operate by binary dividing of the total charge applied to a capacitor array. This process is implemented by using capacitor to attenuate the reference voltage is shown in Figure 1. Advantage of charge scaling DAC is that it is compatible with switched capacitor circuits [1].
