Abstract—This paper presents a Dual Negative Regulated Charge Pumps which is insensitive to process and temperature variations. The Dual Negative Charge Pump makes use of two PMOS transistors to switch on either one of the two negative outputs. The negative charge pump was realized with good line regulation, low ripple voltage and small IC area. Measurement and simulation results show that the Dual Negative Charge Pump meets all the design specifications.
Index Terms—Negative charge pump, regulated, fixed frequency, constant switching frequency.
