An integrated circuit device is provided having one or more pairs of ring oscillator circuits. A per-user metering structure for wireless broadband data services includes a target data throughput allowance provided to the network user for a relatively short time period known as a metering period, where a plurality of metering periods are contained in a billing period. Consequently, the magnetization profiles produced by the RF pulses generated by the system and method described herein will be closer to the desired profiles. The circuit can be used to program and read multiple bits within a single programmable device.
