Mixed Design - Analog with Digital
Mixed Electronic Designs
Digital Interface to Analog Circuits is an example of Mixed
Signal Design. Generating Digital Control Signals from the
Analog sections in instruments is also done by Mixed Signal
Digital Potentiometer - AD5242
A/D Convertors and D/A Convertors are like Mixed Signal Chips. A
Digital Potentiometer that controls an analog signal amplitude
with a digital byte or word, figures in Mixed Design Circuit.
Analog Designs have to handle Linear Signals, Like 2.03 V and
35.3812 mA. Waveforms of all shapes from Straight Line DC
Levels to the Jittery and Multi-Frequency Audio Waveforms.
Digital Designs manage Digital Signals, Like 0 and 5V Logic
levels. All families of digital Logic, have some Threshold
Limits and Voltage windows to determine Data Voltage or Current
levels over Noise; this (Analog) comparator like action
evaluates a High or Low Logic state. There are only two states,
one is Low and the Other is High. 0 and 1 Respectively. The
Third State in the word like Tristate, is a floating high
impedance for Bus sharing between devices.
and Waveform Generators – IC
I would like to understand Mixed Circuit Designs as any circuit
made of Valves, Discretes or Chips; in which both Analog signals
and Digital Signals are Used. That would make an Analog Mux a
Mixed Circuit, so also a PLL and a VCO.

Mixed Interface and Signal
Mixed Signal IC or ASIC are chips that are mainly Digital on the
Core but have peripheral I/O within the chip to interface with
the real world outside, over Analog Signals. Sensors and
Actuators use signals in the analog language. The CPU with its
Math Power, speaks Digital Words, its behavior thus can be
patterned by a Software Program.
Ground and Digital Ground
RF Microwave and Communication Chips; Power Electronic PWM
Integrated Circuits are Specialized Niche Mixed Sub-Domains.
Therefore any Student of Robotics, Multimedia and
Instrumentation, must be good at these Mixed Designs and a
master of C Programming.
