Abstract

In today's paging application, the components within a paging system may include a receiver, a microcontroller, a voltage management IC, and others. A receiver plays an important role in receiving a page without errors. Unfortunately, most of the companion ICs within the pager could possibly gen- erate undesired harmonics that affect the accuracy of the receiver. In that situation, the outputs of these periodic output signals are desired to have slower rise and fall times. The rise and fall time attenuator illustrated in this paper serves a mean to effectively slow down the rise and fall times. In addition, it also reduces the trade off of power efficiency.
