yes, it is not very hard, because the used frequncy is not so high. you can use 0.8u tech easily; but you should have higher power supply and high current!

mos capacitance
When you have a PMOS transistor inside N-Well region your substrate for this transistor is also isolated from substrate of other noisy spaces. This help you when you connect your source terminal to substrate. The other thing is that the NPN transistor (a very weak transistor in...
There are much data about predistortion. for beginning this book has good information in predistortion:
"High Linearity RF Amplifier Design" by Peter B. Kennington
but it is better to determine what you need exactly
harmonic oscillator
it is used when there is no direct way to have such high frequency. thus a fraction of it is used. an oscillator is designed in low frequncies and then the output signal passed through a nonlinear device such a diode. output signal has harmonics of the main frequency. needed...
H-Spice two-tone
use a transient analysis of HSPICE and after some periods see the FFT of output. because it may get much time it is better to take the FFT in MATLAB.
This is high-impedance or Z condition when you don't connect anything to such nodes. The digital circuits always take it az hi because of very high input impedance of the gate and its capacitor. To solve the problem your biasing shouldn't have free nodes.
These are good examples on ADS DesignGuides. you can add them to your project .There are other valuable documents on the ADS website to help you on design and also some ADS projects. some library models are in freescale website.
In spice you can model one block of your circuit with current-controlled and voltage-controlled sources and define it as a subcircuit. for example you can model an opamp with two resistors for input and output and a voltage-controlled current source. at a higher level simulink is very good. like...
because the noise are power not voltage or current and also several sources may not be uncorrelated they are not added in the way that we think about them.
Problems with Hspice
sometims when you choose very low values HSPICE convergence problems happend and some values in its iterations went out of its precision and run time error is shown
rms to dc converter
When your frequency is limited (near 100Hz) you can use microcontrollers such AVR. They have an ADC integrated in them. You should get many samples from your input signal and to have good precision. your ADC freq. may be near 10 times (1MHz) of original signal with 6 or 8...
