Full-wave recifier based on differential difference current conveyor for LV LP application
MetadataShow full item record
In this paper, two full-wave voltage mode and current mode precision rectifiers based on bulk-driven quasi floating-gate (BD-QFG) differential difference current conveyor (DDCC) are presented. The rectifiers are capable to operate under ultra-low voltage (LV) of ±0.3 V and consume extremely low power (LP) in micro range. Moreover, these rectifiers enjoy circuit simplicity, whereas the voltage mode rectifier designed using only two BD-QFG DDCCs, and the current mode rectifier is constructed from only one BD-QFG DDCC and one SOD523 diode from NXP Semiconductor. Thus their circuits are suitable for IC fabrication. Both rectifiers yield better performance in view of the minimum number of devices, reduced power consumption and acceptable operation frequency. The performance of these rectifiers is investigated through PSPICE simulation program using 0.18 μm CMOS technology from TSMC.
