Abstract
An oscillator includes: a first inductor; and a programmable capacitor bank coupled between a first terminal of the first inductor and a second terminal of the first inductor, where the programmable capacitor bank includes a plurality of cells concatenated together, where each cell of the plurality of cells includes a first node, a second node, a third node, a second inductor, and a programmable capacitor, where the second inductor is coupled between the first node and the third node, and the programmable capacitor is coupled between the third node and the second node, where a first inductance of the first inductor is larger than a sum of the inductances of the second inductors of the programmable capacitor bank.
