Title: Level shift circuit
Inventor: OONISHI NORIYASU
IPC: H03K5/003
Filed: 1989-04-13
Abstract: PURPOSE:To reduce the power consumption of a level shift circuit by feeding the output voltage of a differential amplifier back to the control electrode of a MOS transistor serving as a bias source of each source follower circuit of a power voltage converting circuit. CONSTITUTION:When the electric charge is sent to a capacitor C1 from a CCD register 2 via an input terminal IN1 of a charge/voltage converting circuit 1, the output voltage Vout1 is outputted from an output terminal OUT1 in response to the electric charge value. The output voltage Vout2 of a differential amplifier 7 is applied to each gate of MOS transistors M3, M5, M8 and M10 which serve as the bias sources of the source follower circuits of both charge/ voltage converting circuits 1 and 6. In this case, it is just required for the voltage Vout2 to have a level enough to turn on those MOS transistors. Then the amplifier 7 operates with the voltage VCC lower than the voltage VDD. As a result, the power consumption is reduced for a level shift circuit.
