| Popis: | In this paper, we present a novel, piezoelectricactuator driver topology that combines high-voltage actuatordriving in the range of -50 V- to +100 V with piezoelectricreliability. The output waveform is generated by a novelcapacitor clamping circuit (patent# PCT/EP2016/066134) withprogrammable rise-and fall times implemented in a 0.35 umhigh-voltage bulk CMOS technology optimized for capacitivelight-load (2 nF- to 8 nF) operation. The novel piezoelectricactuator driver consists of a negative voltage generator and adegradation regulator integrated onto a single chip. The smartdriver electronics is optimized towards reliable piezoelectricoperation by taking fatigue and electrical overstress intoaccount. The novel piezoelectric actuator driver is the first steptowards self-regulated electrical compensation of piezoelectricactuator degradation which promises increased actuatorlifetime and reliable operation. |
