| titleOfInvention | A High PSRR Hybrid LDO Circuit with Startup Detection |
| abstract | The invention discloses a high PSRR hybrid LDO circuit with start-up detection, including a differential voltage-controlled oscillation circuit, a frequency comparator, a digital control circuit, a single-pole double-actuator switch array circuit, a PMOS array circuit and a start-up detection circuit; its circuit principle First, two clock signals are generated under the control of the reference voltage and the LDO output voltage respectively, and then the two clock signals are converted into switching control signals of the PMOS array and provided to the single-pole double-acting switch, so that it controls the switching state of the PMOS array and makes the output of the LDO. The voltage is changed, and finally the LDO output voltage is used to control the voltage-controlled oscillator to form a negative feedback loop, so that the LDO output voltage and the reference voltage tend to be equal. Therefore, the hybrid LDO circuit of the present invention can provide a start-up detection function in a wireless passive circuit, and can ensure high PSRR performance while realizing a wide bandwidth of the circuit. |
