Title:
レベルシフト回路、並びに、これを用いたアクチュエータ装置及び光スイッチシステム
Document Type and Number:
Japanese Patent JP4487559
Kind Code:
B2
Abstract:
A level shift circuit that shifts both the high potential level and the low potential level of an input voltage, a micro actuator and an optical switch using such a level shift circuit are disclosed. A CMOS inverter 11 connected to a +5 V power source and a 0 V power source provides, in response to an input signal, an output voltage whose H level is +5 V and whose L level is 0 V. A single channel MOS inverter 12 connected to a +15 V power source and the 0 V power source provides, in response to the output voltage of the CMOS inverter 11, an output voltage whose H level is +15 V and whose L level is 0 V. A single channel MOS inverter 13 connected to the +15 V power source and a -15 V power source provides an output voltage whose H level is +15 V and whose L level is -15 V. The inverter 12 has an NMOS transistor Q4 as a drive element. The inverter 13 has a PMOS transistor Q5 of the opposite conduction type as a drive element.
