This post would present you with assembly language program for 16-bit addition in 8085 microprocessor. The following Hex Code is a generic one for both no-carry and carry generation situation. // Manually store 1st 16-bit number in the memory location 2000H & 2001H in reverse order // For Example 1st number = B349H; i.e, 2000<-49H…
This post would present you with assembly language program for 8-bit addition in 8085 microprocessor. We will consider 2 different cases of addition (i) Addition of two 8-bit numbers generating no carry (ii) Addition of two 8-bit numbers generating a carry Addition of two 8-bit numbers generating no carry // Manually store 1st number in the memory…
For the design of any circuit with the CMOS technology; We need parallel or series connections of nMOS and pMOS with a nMOS source tied directly or indirectly to ground and a pMOS source tied directly or indirectly to Vdd. A basic CMOS structure of any 2-input logic gate can be drawn as follows: 2…
These are some of the commonly encountered questions regarding designing a Differential Amplifier – If you want to learn the basic design steps of a differential amplifier, then click here Q-1) When the design technology node changes, say from 180nm to 90nm, what are process-dependent parameters whose values would be changed? A- On the change…
Differential Amplifier is an electronic circuit which amplifies the difference between two input voltage, but rejects any signal common to both the inputs [Source]. Following is the circuit for Designing a Differential Amplifier- You may also face these questions while designing a differential amplifier. Differential Amplifier can be designed by following 5 simple steps –…
Memory devices are something which retain data for a time period just like human brain. This post classifies the Semiconductor Memories and maps different memory devices to Computer Memories. Semiconductor Memories Semiconductor Memories can be classified based on two different characteristics: (i) Access Type (ii) Data Retention Capability Note: Hard-Disk, CD, DVD, Floppy-Disk, Magnetic Tape are also…

Verilog and VHDL are Hardware Description languages (HDL) that are used to describe the behavior and structure of electronic systems. HDL languages are different form software language like ‘C’, as they use concurrency constructs to simulate circuit behavior. HDL includes a means of describing propagation time and signal strength. Verilog Vs. VHDL
Static CMOS circuits use complementary nMOS pulldown and pMOS pullup networks to implement logic gates or logic functions in integrated circuits. Dynamic gates use a clocked pMOS pullup. The implemented logic function or the logic gate is achieved through 2 modes of operation: Precharge and Evaluate. Advantages of dynamic logic circuits: 1) The number of…
