Patent JP-H04234209-A (JP)
Title: Class ab cmos amplifier
Inventor: KURISHIYUNASUWAMII NAGARAJI
IPC: H03F1/30
Filed: 1991-07-19
Abstract: PURPOSE: To reduce a static current and to improve phase response by connecting a source follower FET, a current control FET and a load FET in series on a level shift stage connecting an input signal to the gate of the source follower FET and connecting reference voltage to the current control FET. CONSTITUTION: An input amplifier 20 applies an input signal having Vdd as a reference to a lead wire 21 to impress the input signal to the gate of an output FET 50. The output of the amplifer 20 is biased so that the static voltage of the lead wire 21 is reduced from Vdd only by about the threshold of the FET 50 and a small static current is allowed to flow into the FET 50. A reference voltage generator for applying constant voltage to a node 35 is formed by diode-connected FETs 31 to 33. When the relative sizes of respective FETs are determined with prescribed relation, the level of reference voltage on the node 35 becomes voltage allowing a small static current to flow into a level shift stage consisting of FETs 41 to 43 and phase response can be improved.
