Dual Negative Regulated Charge Pump
Keywords:
Negative charge pump, regulated, fixed frequency, constant switching frequency.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.
