摘要：
A high-voltage (HV) bidirectional current sensor using fully-differential amplifier (FDA) is designed and analyzed in this investigation. The FDA balances bidirectional input voltages of the HV current sensor by a feedback loop. Thus, the proposed design can detect the direction and magnitude of the current by the difference between the output voltage and a reference voltage. Detailed analysis, including the method of the HV current sensor, is reported. All-corner post-layout simulations of the proposed HV current sensor justify the maximum error <= 1.43 % in the range of +/- 8 similar to +/- 20 V.
