Hello Dear Readers, Currently, at Analog Devices Bangalore vacancy for AMS Engineer role. Analog Devices designs and manufactures semiconductor products and solutions. We enable our customers to interpret the world around us by intelligently bridging the physical and digital worlds with unmatched technologies that sense, measure and connect. Analog, Mixed-Signal Verification Engineer focus on verification of high performance data converters. Job responsibilities: Learn AMS verification methodology and CAD tools Development of analog/behavioral models Validation of models to cross-check with the actual design behavior Create and own test verification as per the test plan to ensure high quality of design block Work closely with design team for complex debugs to resolve verification failures Run regressions and manage regression failures Skills Required: Basic understanding of VLSI circuits. Good knowledge of Verilog RTL coding including state machines, adders, multiplier...

  Hello Dear Readers, Today, I will explain how to design a Layout in the MAGIC layout tool and how to perform SPICE simulation. CMOS inverters (Complementary NMOSFET Inverters) are some of the most widely used and adaptable MOSFET inverters used in chip design. They operate with very little power loss and at relatively high speed. Furthermore, the CMOS inverter has good logic buffer characteristics, in that, its noise margins in both low and high states are large. A CMOS inverter containing a PMOS and an NMOS transistor connected at the drain and gate terminals, a supply voltage VDD at the PMOS source terminal, and a ground connection at the NMOS source terminal Vin is connected to the gate terminals, and Vout is connected to the drain terminals As shown in Fig.1 is a circuit-level symbol but in the layout-wise internal structure of CMOS is consisted of common P-Type Substrate for building NMOS and N-Well implanted for building PMOS as shown in Fig.2.         ...
