## Abstract A direct digital frequency synthesizer (DDFS) using on‐chip CMOS one‐time programmable read‐only memory (OTP ROM) is presented. A straight‐line approximation algorithm for sinusoid with compensation is adopted such that the accuracy could be maintained and the cost is reduced. Most impo
## Abstract A 2.60‐GHz integer‐N frequency synthesizer was designed and implemented in SiGe BiCMOS technology. The single chip includes fully integrated VCO (voltage control oscillator) as well as LPF (loop‐filter). The synthesizer provides a wide frequency range of 300 MHz, which covers 2.59–2.66
