High Impedance Amplifier Circuits

CMOS Logic Inverter Amplifier Characteristics
This chart shows some of the measured characteristics of three different unbuffered CMOS logic gates, used as voltage amplifiers.

ELECTRIC FIELD DISTURBANCE MONITOR
This schematic is the power supply and front-end sections of the field monitor that is discussed in more detail at Electric Field Disturbance Monitor. The system can detect human and animal motion by the electric fields they disturb.
