A Transconductance amplifier is to be used to interface a voltage signal Vs(t) to a resistive load R(L)=5k ohms. The signal source is represented by a Thevenin equivalent circuit with a source resistance R(S)=20k ohms. The design is to provide an overall voltage gain G(v) such that Vo(t)=10V Vs(t), ie., G(v)=10V/V. The problem is to define the parameters of a transconductance amplifier (Ri. G(m), and Ro) for this use. These parameters must be selected to fall within the following range:10K<R(i)<25k ohms1mA/V<G(m)<10mA/V5k<R(o)<20k ohmsSelect suitable values for the amplifier parameters and show that an overall voltage gain G(v)=10V/V is obtained. Also find the overall gain G(i)=i(s)/i(i) and power gain G(p)=p(s)/p(i) for the amplifier.
Discuss the different analog-to-digital converter (ADC) types and configurations. What is the purpose of the ADC. How do you interface to the different configuration
A tractor-trailer truck driver friend often delivers to companies that do not have a fork truck or loading dock. She wants to install a lift-gate on her trailer so she can load and unload her truck without a fork truck.
