    摘要: A fluid jet head with driving circuit of a heater set. A first and a second primary transistor are coupled to a first and a second heater. When the first primary transistor is turned on under control of a first control voltage and a first current is generated flowing through the first heater, the first primary transistor, and the first current path, then the first primary transistor has a first primary equivalent resistance corresponding to the first control voltage. When the second primary transistor is turned on under control of a second control voltage, and a second current is generated flowing through the second heater, the second primary transistor, and a second current path, then the second primary transistor has a second primary equivalent resistance corresponding to the second control voltage. Therefore, the thermal energy generated by the first heater is substantially equal to that generated by the second heater.

    摘要: The state machine with hysteresis provided in the invention includes a current state circuit and a next state control circuit. The current state circuit, in response to a clock signal and a control signal, generates a current state signal and a frequency detection signal. The current state signal has a plurality of bits. The next state control circuit, in response to the current state signal and the input signal, generates the control signal. A hysteresis is observed with regard to the relation of the frequency detection signal with respect to the frequency of the input signal.
