Abstract :
A 1.6 Gb/s SiGe baseband ΔΣ modulator with integrated wideband mixer for RF applications is presented that exhibits 65 dB spurious-free dynamic range over a 50 MHz bandwidth centered up to 1 GHz. Also, a concept is introduced for applying this architecture to monolithic receiver implementations
