Abstract
A 24-㎓ direct-conversion receiver frontend is presented for in-cabin applications. The proposed RF receiver is composed of a low-noise amplifier, an I/Q down-conversion mixer, and an I/Q local oscillator (LO) generator circuit. An inverter - type transconductor with third-order nonlinearity cancellation is applied to the I/Q down-conversion mixer to improve the linearity of the I/Q down-conversion mixer. By adopting a linear I/Q down-conversion mixer and a balanced I/Q LO generator, the 24 ㎓ receiver front-end obtains high linearity and good I/Q balancing performance. The receiver front-end draws 21-㎃ current from a 1.2-V supply voltage. It shows a conversion gain of 30.4 ㏈, noise figure (NF) of 4.5 ㏈, and an input 1-㏈ compression point (input P1㏈) of -23 ㏈m in the 24-24.5 ㎓ range.
