NMOS LDO based on hybrid modulation bias current generation circuit

The invention belongs to the technical field of analog circuit power management, and particularly relates to an NMOS LDO based on a hybrid bias current generation circuit. The invention provides a hybrid modulation bias current generation circuit for an NMOS LDO and a low-power-consumption oscillator circuit. According to the hybrid modulation bias current generation circuit, the bias current of the LDO can be dynamically adjusted when the load transiently changes, the bias current is adaptively changed according to the magnitude of the load current, so that the transient response is improved on the premise of ensuring low static power consumption, compared with other schemes, the circuit can adjust the static current more quickly even when the load is light, and the stability of the circuit is improved. Therefore, the loop bandwidth and the slew rate of the error amplifier are improved. The low-power-consumption oscillator circuit can output a clock signal of which the frequency is in direct proportion to th
