A Closed-Loop Reconfigurable Analog Baseband Circuitry With Open-Loop Tunable Notch Filters to Improve Receiver Tx Leakage and Close-in Blocker Tolerance

This brief presents an analog baseband (ABB) circuit in a 0.13 \boldsymbol{\mu }\text{m} SiGe technology for transmitter leakage cancellation and close-in blocker suppressions in fully duplex (FD) frequency-modulated continuous-wave (FMCW) radar. This ABB comprises a programmable gain amplifier (P...
