Many applications call for wide-range-tunable LC oscillators that can deliver a nearly constant-frequency, nearly harmonic-free output even when the circuit's output load changes. From a design ...

This Design Idea applies a noveltopology to an oscillator. It usesa series-connected LC (inductive-capacitive)tank circuit to give the circuita higher tuning range than circuitsthat use a parallel-LC ...

Figure 1: The system and the operation principles. We have carried out two types of measurement. In the first, a response analysis, the LC tank circuit is driven near-resonantly by a low-frequency ...

Voltage-controlled oscillators (VCOs) are pivotal components in modern communications and signal processing, where their ability to generate a stable yet tunable signal is paramount. The performance ...
