Principles of Transistor Circuits: Introduction to the Design of Amplifiers, Receivers and Digital Circuits

However, amplification is useless without selection. This is where —from simple AM radios to sophisticated superheterodynes—demonstrate the true elegance of transistor circuits. A receiver must pluck a single, weak radio signal from a sea of electromagnetic noise. Here, transistors are combined with tuned circuits (inductors and capacitors) to create selective amplifiers . A resonant circuit at the input allows only a desired frequency to reach the transistor base. The transistor then amplifies this selected signal. This is the story of how to think like a transistor

Crucially, the same physical transistor in a smartphone radio receiver (an analog circuit) is also the same physical transistor in its CPU (a digital circuit). The only difference is the biasing and the signal swing. This integration is what makes the (SoC) possible, where analog front-ends (receivers) sit millimeters away from billions of digital switches. The designer must now contend with new challenges: digital switching noise corrupting sensitive analog inputs, and the need for mixed-signal design where analog-to-digital converters (ADCs) form the bridge between the two worlds.
