Parameter Conversion: S to Z Y h T

When an RF Engineer starts designing a circuit, there comes a time where s/he encounters s-parameters. Looking at that s/he needs to make a call on the different other parameters like h-, Z-, T- or Y-. Is there a tool which does it for you? YES, there is !! A web based calculator which can do the conversion of S-Y-Z back and forth. How does it do that ? The formulae which allow us to go through with the rigour needed are available in most texts and scholarly articles. But for the people in the MATLAB zone, there is the RF ToolBox which has the s2z converter function to do the needful. Hey, hello !! Hold on!! What are you talking about ? The 2-port network shown above is representative of that implied in the application of these equations. All of the parameter equations make use of complex values for all numbers of impedance and the resulting matrix parameters, i.e., Z = R ± jX. Z 01 and Z 02 are the complex impedances of ports 1 and 2, respectively; simi...

Continuous Time Sigma Delta ADC

A few links that explain techniques and suggestions that active Analog Circuit Designers can use. Current Steering DAC is a commonly used circuit to go along with Multi-bit quantizer for Sigma Delta Converters. For a very interesting discussion on them for verilog modelling, read here . Quantization and Voltage Dynamic Range - here Measuring SNR and PSD for SD ADC implemented on a FPGA Simulating a DSM in Simulink Hope these help you get started with designing a Sigma Delta ADC. Cheers !! Edit: When you characterize your Silicon, you tend to realise that absense of a screw/nail causes more trouble than the absense of a major testing equipment. The respect towards the smaller things in life increases drastically. Some more links for the information are given below: Plotting PSD and SINAD of an ADC in Cadence. One of the best links links that I have found in recent times.

Nostalgia ! - Didi - Cheb Khaled

It was nearly two decades ago that I heard this song for the first time. It was a great catchy tune, of those time. I thank Doordarshan and All India Radio for introducing me to this song. The first Arabic / Algerian music that I heard. I never understood the lyrics then. I just used to enjoy the line "... didi didi didi ...". I came across this song on my presumed-long-lost-playlist when I was cleaning my HDD. It instantly brought back memories of the times, when my cousins and I, danced on this song in all family gatherings. I loved the artist for his voice. I didn't know his name till about 2-3 years ago. ' Khaled '. What a voice ! There have been many versions and renditions by many artists globally. But this song, still survived the sands of time. O! people of the 90's, I present you once again.... 'Didi' Here are the translation of the lyrics (Source: Issam Abdelghaffar ): (I'm burning in the fire of love but you're not) ...
