Diode compensates distortion in Amplifier stage - 09/16/04 EDN-Design Ideas The
voltage amplifier in Figure 1 exhibits smaller nonlinear distortion than does the
conventional amplifier in Figure 2. Diode D1 compensates for the distortion inherent
in the npn transistor. The voltage gain of a common-emitter amplifier depends on the
transconductance of the transistor. The transconductance of the bipolar transistor is
as follows where e is the charge of an electron,.... [Design Idea by S Chekcheyev,

Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High
Speed Systems - AN-417 Analog Devices Application Notes (app note added 6/06)
Movement towards lower power supply voltages is driven by the demand that systems
consume less and less power coupled with the desire to reduce the number of power
supply voltages in the system. The following applications are discussed: Single-Ended
and Differential Input ADC Input Circuits, Video Line Driver,....
Force/sense connection eliminates
multiplexer on-resistance error - 22-Jan-04 Issue of EDN Digitally controlled
gain is an everyday analog-design element. You frequently find this element in an
op-amp-based, transimpedance current-to-voltage converter. When you design digital
gain control into such a converter, the usual scheme is to arrange things such that a
digital multiplexer selects the appropriate feedback resistor for each gain figure....

Full-wave rectifier has programmable gain - 11/09/00 EDN-Design Ideas The
traditional approach to the design of a full-wave rectifier (Figure 1) is to set the
gains of IC1 and IC2 to 1 and use the….PDF contains multiple circuits, scroll to find
