摘要：

A high accuracy frequency/voltage (F/V) conversion circuit for the frequency signal of a piezoelectric quartz crystal (PQC) chromatographic detector is described. The circuit is based on time-division multiplex technology and ladder network digital/analog conversion. The maximum output voltage is 1.5V. With this circuit, the signal of PQC detector, which is delivered to the chromatographic workstation, can be recorded in real-time, integrated and calibrated.
