In this paper, we proposed a new minute phase difference measurement circuit. The conventional circuit is composed of OPA (Operational Amplifier). However, the amplitude adjustment is manual and measurement time is long. The proposed circuit is composed of the minute phase difference measurement circuit with OTA (Operational Transconductance Amplifier), and the automatic amplitude adjustment circuit with FPGA (Field Programmable Gate Array). And the measurement time of proposed circuit will be short. The performance of the proposed circuit is evaluated by Verilog-XL simulation. Simulation and experiment results show that the proposed circuit is able to the automatic amplitude adjustment, and measurement time is short.
