Description
Summary:This manuscript presents the architecture of a hardware-efficient all-digital acoustic borehole telemetry transmitter for use in the Measurement While Drilling (MWD) systems that are intended for the oil drilling service industry. The transmitter employs Direct Digital Synthesis (DDS) for carrier generation to mitigate the effects of carrier generation using analog approach, which is more susceptible to changes in device characteristics in high temperature environment. A hardware-efficient implementation of a Pulse Width Modulator (PWM) is presented to minimize silicon area as typically, the 0.8-/1-μm SOI-CMOS technology is adopted for high temperature electronics.
