GaAs E/D process low-power-consumption phase inverter circuit

Abstract

According to the GaAs E / D process low-power-consumption phase inverter circuit, Vin is a TTL control logic level, voltage reduction is carried out through six diodes, and a TTL logic control signal is converted into -4 / -5V of high and low levels capable of meeting the requirement for opening or closing a GaAs E tube. A drain electrode of a D tube (DM1) at a potential translation tail end is connected with a grid electrode of an E tube (EM3) in a first-stage phase, a first-stage output (Vout1) is connected with a drain electrode of an E tube (EM4) of which a grid electrode is connected with a source electrode, is connected with a grid electrode of an E tube (EM6) in a second-stage phase, and serves as a second-stage output (Vout2) through a drain electrode of the E tube (EM6). And finally, a pair of complementary differential signals is obtained, and the output high and low levels are respectively 0 / -4.95 V, so that the requirement of turning on or turning off a GaAs switch can be met. Grid electrodes and source electrodes of the D tube (DM2) and the D tube (DM5) are mutually connected to form a constant current source, and static power consumption is reduced through a stacking structure and a series resistor mode.

technical field [0001] The invention relates to the technical field of inverters, in particular to a GaAs E / D process low-power inverter circuit. Background technique [0002] figure 1 It is a structural schematic diagram of an inverter circuit in the prior art. In the inverter of the prior art, the TTL logic control level is converted into -4 / -5V which can meet the high and low level requirements of the GaAs E tube to be turned on or off through the potential shift circuit, and then converted into The high and low levels are -4.75 / 0V, and then converted into an inverse complementary voltage of 0 / -4.75V through two stages of inversion. The entire inverter converts the TTL logic control level into a pair of complementary differential signals through four stages of inversion. [0003] The drain of the potential shift output point D tube (DM1) is connected to the gate of the E tube (EM3). By controlling the switch of the E tube (EM3) to control the conduction or shutdown of ...

Problems solved by technology

[0005] However, prior art ( figure 1 ) has strict requirements on high and low levels. If the voltage value deviates slightly, the inverter will not work properly. The number of reversed phases is large, the static current is large, and the power consumption of the inverter will be increased.

[0006] figure 2 However, it is the simulation result of the inverter in the prior art, it can be seen that the quiescent current is relatively large, and the deviation between the low-level output and the power supply voltage is slightly larger
