The Tie Cells are small circuits used to connect (or tie) gates or input logic gates to vdd power or ground. [Read more…] about Tie Cells in IC Circuits: WHY? schematic and explanations
Nmos and Pmos LDO: Differences and Advantages on each Topology
Why are the LDOs mainly built with pmos as a pass transistor and not with nmos devices? [Read more…] about Nmos and Pmos LDO: Differences and Advantages on each Topology
2-phase Non Overlapping Block for Oscillators
Often, we need complementary clock signals where only one clock edge is active at a time. Meaning that the rising and falling edges of the clock are separated in time. In the following diagram, we can see it clearer… [Read more…] about 2-phase Non Overlapping Block for Oscillators
Where is the 0.7V voltage drop of BJTs coming from?
Where can we obtain the ON-voltage or forward-bias voltage in bipolar transistors, which is around 0.7V? [Read more…] about Where is the 0.7V voltage drop of BJTs coming from?
Design a CMOS Comparator with Hysteresis in Cadence
There are many types of comparators, in this example a comparator with hysteresis is analyzed and simulated. [Read more…] about Design a CMOS Comparator with Hysteresis in Cadence
Noise types in CMOS circuits: Thermal, Flicker and Shot Noise explained
Noise is a critical and important factor in achieving high-performance integrated circuits. To design analog circuits, at least a basic understanding of noise is required. [Read more…] about Noise types in CMOS circuits: Thermal, Flicker and Shot Noise explained
