| description | A new capacitive transducer using a
pseudodifferential-input–single-ended output topology for lowpower
portable applications is presented. This is based on a
switched-capacitor chopper-stabilized pseudodifferential integrator
structure that is cascaded with a chopper-stabilized differential
difference amplifier, consisting of a single output and a bandpass
ac output. The measured results have shown that the transducer
integrated circuit, with a sampling rate of 64 kHz in a 0.6-μm
CMOS technology, dissipates 820 μA at a 3.3-V supply and
exhibits a low noise characteristic. For a 100-Hz bandwidth, the
input-referred minimum detectable capacitances are 57.24 and
33.82 aF with reference to the single output and the bandpass
output, respectively. |
