This article presents the design of a high output compliance, very-high output impedance single-ended charge pump implemented using a new low-voltage current mirror. The output current is sampled and a feedback loop forces it to be equal to the desired reference current. This results in a very-high output impedance over a very wide output voltage range, accurate Up/Down current matching, and low transient glitches. The proposed charge pump was implemented using STMicroelectronics 1-V 90-nm CMOS process. Simulations using Spectre show that the Up/Down output currents remain constant and matched within 1% over a charge pump output voltage ranging from 119 to 873mV. Monte Carlo process variations and mismatch simulations indicate that the 1-@s standard deviation between the Up and Down current components is 1.4@mA, or 6.8% of the nominal 20@mA charge pump current at either end of the output voltage range. |
