Due to the absence of internal nodes, inverter-based Gm-C filters [1,2] allow achieving bandwidths beyond what is possible with opamp-RC techniques. The inverter’s class-AB behavior, together with the high transconductance per quiescent current, results in a high dynamic range per power when optimally biased [3]. The major disadvantage of traditional inverter-based GmC filters is that they are ...

Standard lowand medium-power induction motor drives are based on the pulsewidth modulation (PWM) voltagesource inverter fed from a diode rectifier. The dual topology, based on the current-source inverter/rectifier structure is used in mediumand high-power applications. This paper analyzes the existing motor drives based on current-source topologies and proposes a control strategy that addresses...

In this paper, a high frequency contactless power transfer (CPT) system is designed with ∅2 inverter drive. This system works in 30MHz frequency and 380W power with low voltage stress and considers the inductive link parasitic capacitor effect. In the design, we formulated the inverter equations first and then suggested another design for the transmitter and the receiver coils as the energy tra...

This communication presents the evidence of a degradation effect causing important reductions in the delay of a CMOS inverter when consecutive input transition are close in time. Complete understanding of the effect is demonstrated, providing a quantifying model. Fully characterization as a function of design variables and external conditions is carried out, making the model suitable for using ...

Class E Resonant Inverters are theoretically capable of delivering any power to a load and achieve 100% efficiency at any frequency of operation. In practice efficiency in the “high 90's” can be achieved into megahertz frequencies regardless of inverter output powers. The topology also allows the manipulation of output power through sub-optimal operation, with a negligible efficiency penalty. T...

A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...

In inverter design for electric vehicle applications there are several major requirements that should be met. The inverter should be able to operate bidirectionally with reasonably high efficiency under a high ambient temperature. Therefore it is critical to select the suitable main switches for the inverter. In this paper seven types of devices (including 3 dual IGBTs, 1 intelligent dual IGBT,...
