A novel approach to use a voltage‐controlled oscillator (VCO) as the first integrator of a high‐order continuous‐time delta–sigma modulator (CT‐DSM) is presented. In the proposed architecture, the VCO is combined with a digital up–down counter to implement the first integrator of the CT‐DSM. Thus, the first integrator is digital‐friendly and hence can maximally benefit from technological scaling.
