High Frequency Models of BJT, MOSFET and Ckts

 When input signal to an amplifier is in the range of 10-100 KHz we use small signal-low frequency model of the transistor for analysis.



With increasing frequency πŸ“ˆ , internal capacitance of the transistor starts affecting its performance strongly πŸ“ . A low frequency model cannot work well in this situation 🚧 .

To accommodate these performance changes of the transistor, a separate model is developed for high frequency operations.


In the following handwritten notes I have covered the most important topics in detail :

* πŸ’‘ High frequency model of BJT

* πŸ’‘ High frequency model of MOSFET

* πŸ’‘ Miller Effect

* πŸ’‘ Different approaches to do Frequency Analysis

* πŸ’‘ Input Capacitance and Output impedances

* πŸ’‘ Frequency response of differential circuits, cascaded stages, MOS cascode

HARRY POTTER AND MYSTERY OF CORE JOBS

Image
It is rather mystique to discover the correct path and even mysterious to find a mentor - specially when you're preparing for a core job! My preparation fueled on oiling my ears to hear every advice my seniors were giving and eavesdropping on my peers' preparation strategies. The following is a fine collection of all the resources that are sufficient to crack any CORE job : First up, we need to know the terra-incognito, the uncharted and unmastered lands. All the places we need to be - to gather the arsenal to champion placements. Following is the list of all the subjects we need to be proficient ( at-least familiar) in: 1. Digital Electronics πŸ“± 2.Analog Electronics  ⏰ 3. Computer Architecture and Microprocessor ( COA,8085/86/ARM )πŸ’» 4.Hardware language ( Verilog/VHDL  ) δ·” 5. Miscellaneous ( Projects, Aptitude, scripting languages- Perl, python, LINUX, etc ) ❓ After knowing the places we need to be, let's start filling in the details on the map:  There are different...

So, You WANT a job in VLSI CORE ? πŸ‘€ --- You should DEFINTELY OPEN ME!

Image
If you are reading this article, you have already experienced VLSI in it’s finest. VLSI or Very Large Scale Integration is a highly technical field. You can assume it as SPHINX of technology which has wings of programming, head of a researcher and body of detective and tail of a technician . The field focuses on integration of millions of transistors into a smaller package and make that sophisticated package work! These packages are affectionately called β€œ chips ”. People love these chips, and these chips like to be addressed as SoC or ASICs . IC Design Flow                                            VLSI industry is sapiosexual and hence require special understanding and grasp of subjects to be impressed. Entering VLSI industry is tough, but it becomes excruciatingly harder if you don’t know your battle. First step while choosing your battles is to understand the battle groun...

Alice in the wonderland of Formal Verification

Image
  A verification engineer is a detective for Silicon – a Formal verification engineer is a verification engineer on steroids. If you Google, β€œ How much time is spent on verification in RTL Development ?” You will find yourself uttering one of the many adjectives of great surprise! Design Verification takes almost 80% of the overall time spent on chip development and verification engineers lose hair, sleep, peace, patience and a pinch of weekends on tight deadlines to deliver the quality of verification. Any attempts to cut short the efforts or expedite the process is a giant leap in correct direction. Formal verification is rising and shining like a superhero in the ever-growing complex field of verification. It is the ring of power in the current market and surely gives a boost to your career in FrontEnd Verification . Being skilled in Formal Verification ensures you a ticket to be highly employable in semiconductors at-least for the next decade.  Formal Verificat...
