摘要：
In this paper we present a design for a two-wire telemetry and signal conditioning circuit for piezoelectric sensors. The telemetry system uses an on-chip voltage regulator as part of the signal-vs-supply filter. We also introduce a new shielded-base bipolar opamp design that exploits the properties of both MOS and bipolar transistors. The new design results in 10X reduction in power for a 10dB reduction in signal-to-noise ratio. For this design the bandwidth of interest is 10KHz to 1MHz and the sensor capacitance size is 100pF.
