A manner by which to effectuate closed-loop power control in a two-way communication system. A switched-current, exponential DAC (digital-to-analog converter) is utilized to generate a reference signal responsive to detection of successive power control bits received by the communication device. The reference signal is step-wise exponentially related to previous values, thereby to cause a step-wise increase, or decrease, in the value of the reference signal. The reference signal is utilized to effectuate an increase or decrease in the power levels of signals generated by the communication device. |
