A High Frequency Active Voltage Doubler in Standard CMOS Using Offset-Controlled Comparators for Inductive Power Transmission

Abstract: In this paper, we present a fully integrated active voltage doubler in CMOS technology using offset-controlled high speed comparators for extending the range of inductive power transmission to implantable microelectronic devices (IMD) and radio-frequency identification (RFID) tags. This active voltage doubler provides considerably higher power conversion efficiency (PCE) and lower dropout voltage compared to its passive counterpart and requires lower input voltage than active rectifiers, leading to reliable an… Show more

“…In an integrated circuit (IC) implementation, there are two choices for implementing D 1 ; a passive Schottky diode or an active diode [18]. The conduction time of D 1 is much smaller than 1/ f p , which indicates a need for rapid on/off operation of the active diode.…”

“…Although several power management integrated circuit (PMIC) solutions have been proposed to achieve higher power conversion efficiency (PCE) [17]–[19] in the WPT, these systems cannot improve the PDL. Boost converters [20], [21], charge pumps [22], [23], and voltage-doubler rectifiers [18] have been implemented in the WPT system to boost the Rx received voltage by reducing the effective load resistance. These techniques can increase the output voltage on the Rx side at the cost of system complexity and large number of off-chip components, resulting in increased Rx size.…”

“…An unbalanced-biased comparator with non-zero turning-off trigger voltage is proposed to shut off the rectifying transistors when the induced voltage is smaller than the rectifier's output voltage [9], but the turn-on delay of the rectifying transistor is not compensated, leading to power loss. High-speed and compensated biasing comparators are also reported to control rectifying switches, but extra current is consumed [24], [26]. More critically, if those circuit techniques were directly applied to the HV rectifier, more power would be dissipated due to the much higher supply voltage used by the rectifier control circuitry.…”
