| 摘要 | A reference voltage generation circuit includes an auto-activation unit, an operational amplifier unit, and a tail current resistor. An input of the operational amplifier is grounded via the tail current resistor. The auto-activation unit is coupled to the operational amplifier so that the circuit operates at an operating point. A reduction of current noises, circuit area, and overall cost occurs implemented through the described tail current unit | ||
